Hi All,
I d like to buy HTC thunderbold with out contract.
i have a question that i could not find an answer.
Is there a way to unlock this and use with another GSM (other than Verizon).?
Thanks

We use GSM tech for our LTE, hence the reason we have a SIM card.

Um, this is incredibly wrong. This is like saying, "My car runs on diesel, hence the reason it has a hitch." Like a hitch has nothing to do with whether or not a car runs on diesel, a SIM card has nothing to do with whether or not a phone runs on GSM (at least anymore - that might have been true at one point but most certainly not now). Our SIM card is specifically for LTE (and perhaps for eHRPD - I'm not sure about that). LTE does NOT use GSM technology. Sorry, that is just plain wrong.

Either you're a troll or too lazy to google (or both).
3GPP Long Term Evolution (LTE), is the latest standard in the mobile network technology tree that produced the GSM/EDGE and UMTS/HSPA network technologies.[1][2] It is a project of the 3rd Generation Partnership Project (3GPP), operating under a name trademarked by one of the associations within the partnership, the European Telecommunications Standards Institute.

http://en.wikipedia.org/wiki/3GPP
http://en.wikipedia.org/wiki/Ultra_Mobile_Broadband
LTE has far more in common with GSM than CDMA does and won the support of the 3GPP standards board (something CDMA never was, but GSM is) and is the next natural progression from the current GSM standard (not so natural for CDMA networks like verizon and sprint, hence the need for eHRPD as a bridge between). However, it is supposed to eliminate the disadvantages of both GSM and CDMA technologies. CDMA (qualcomm owns the rights) is not an open standard, while LTE is open. It happens to be the standard that nearly every major wireless carrier is going to throughout the world, so in the near future, a phone with both voice and data over LTE will be a "world phone." Qualcomm was developing their own 4g standard to succeed CDMA2000 but dropped it in support of LTE instead.
Unlike GSM/UMTS carriers like AT&T, Verizon's transition to LTE wasn't a natural evolution because they had to change from High Rate Packet Data (HRPD) to LTE. This meant that they needed to choose a migration path factored by radio access strategy, network resource strategy, services enabled, timing and cost. While moving to LTE service their goal was to simplifying interworking with non-3GPP mobile networks, which is essential for CDMA carriers migrating to LTE.

ATT and Tmobile (if FCC allows the buyout) wont need something like eHRPD because LTE is a the natural next step transition for them from their current version of GSM (due to happen sometime next year or so) unlike Verizon with cdma, hense the need for it to handle things.
Verizon has decided to use eHRPD as their upgrade path to 4G, which allows them to update their existing HRPD packet core using SAE/EPC architecture. The primary benefit that eHRPD offers is the handoff between cellular towers - you maintain the same private IP when you move from location to location. With this new protocol operators will be able to optimize cellular handovers, which should reduce dropped sessions and decrease the handover latency.

eHRPD has nothing to do with the sim card, it's just a means of transferring packets (and handoffs) in a more efficient way between 3g 1xEV-DO (CDMA) and LTE (3GPP/GSM) at the carrier tower level. It's a bridge technology between the two, nothing more. Without it, more people would be complaining about the slowness of handoffs between LTE and 3g (like they were a week or so ago).
Really guys, go do your own fact checking sometimes and don't take everything said on the boards as fact.

None of the three.
Absolutely nothing you posted stated that LTE is the same as GSM technology.
You argued that it more-closely resembles GSM than CDMA - why are you arguing this? I never said anything about it resembling CDMA. In fact, I disagree with nothing in your post other than my being a troll or being too lazy to Google. Absolutely nothing you said contradicts anything I said.
"[LTE] is the latest standard in the mobile network technology tree that produced GSM" - This in fact agrees with my statement! LTE technology is DIFFERENT than GSM technology. Perhaps it evolved from GSM, but that very definition makes it a different technology!
Now if you think I am wrong, then please prove to me in any way, shape, or form that the Thunderbolt can run on any GSM network. Please do this.

I never said it wasn't built upon GSM! Jeesh, people!
I said they were not the same technology. I meant to imply that they were directly incompatible. Whether I successfully implied that or not doesn't change the validity of what I said. LTE technology != GSM technology. To the best of my knowledge, there are no LTE devices that work on GSM networks via the LTE radio. And I guarantee that no GSM phone works on am LTE network. If they were the same technology, then, well, we would have had 20mbps downloads years ago.
Why do people insist on putting words in my mouth? I can very easily put words in your mouth and call you stupid. It doesn't make me any more right.

Read the parts that are bold, maybe I just forgot how to read though. This was from your post, I didn't add any words.
The first generation of dual core desktop CPUs "used" the previous generation's CPU technology by simply slapping two of them in one chip with additional management technology to consume the old technology. The second generation of dual core desktop CPUs modified that technology (not "used") to have native multi-core technology but did not "use" the old technology (it evolved it).
Unlike the first generate of dual core desktop CPUs, LTE does not "use" GSM technology - it's a modified version of it. It's a different protocol, there are different rules, and it is a different (modified) technology.
Perhaps we're both arguing the same thing and don't realize it due to some communication failure on one or both parts? Hell, I'll take the blame and claim I'm communicating poorly. This conversation isn't going anywhere and isn't helping anybody.

So I was thinking about the tbolt, and realized something that I believe is interesting:
It's pretty common knowledge that Verizon CDMA does not currently support simultaneous voice/data, a huge grievance for many a verizon iPhone owner. The Thunderbolt is touted to be the first device that can handle this function and will do so by handling voice over the CDMA network and data over the LTE network. Makes sense, sounds good and all right? BUT....I was thinking about coverage of LTE and how it's pretty scarce for now and was wondering what would happen if you were not in an LTE area and using the Tbolt? Wouldn't the absence of the LTE network effectively stifle your ability to use data while on the phone?
Does anyone have any info on this or remember reading anything about it? It seems to me that it is entirely possible that the Tbolt will have the same limitations over simultaneous voice/data as the iPhone and other smartphones as long as the user is in a non-4G/LTE area. I am lucky enough to live in a 4G/LTE area so this wouldn't be a huge factor I guess but some people were really looking forward to having that capability.
Unlike all the rumors, the phones has two radios.
1 - 1x voice/data radio
2 - EVDO / LTE radio
The phone will do simultaneous voice and data in both 4G and 3G areas. Only issues is that two radios means increased battery drain

Your post makes no sense bud. The phone has the following specs:
CDMA 1X/EVDO Rev.A: 800/1900MHz
CDMA LTE - 700MHz
Rev A Capable
The phone has one of 2 possibilities:
1. In an area with no 4G coverage, the phone will simply not work as advertised. It will act just like any other 3G smartphone.
2. The more likely option, and I say likely mostly because they like to avoid class actions: Verizon partly delayed the phone in order to upgrade the towers and networks with the ability to process 3G data and calls simultaneously.

if that second option were true, wouldn't that mean that every phone currently running on 3G (iphones and droids alike) would all gain the ability to run simultaneous data and voice? that sounds very nice indeed.
i don't have any sources but i believe i remember reading that the nature of CDMA and how it connects prohibits simultaneous voice/data as opposed to however GSM operates. sorry for such broad information but i'm not exactly a wireless carrier expert. if what you said is true though and they found some way to upgrade it, that would be awesome for all those on verizon 3G.
my skeptical side though is saying that verizon is no saint and would just respond that simultaneous voice/data is a feature specifically for 4G service and if you aren't in a 4G area tough break and wait for 4G/LTE to roll out near you.
Actually VZW recently did a software upgrade for their infrastructure to allow simultaneous voice and data over EVDO Rev A and the Thunderbolt is their first handset with the radio capable of supporting it. From what I've read it's a hardware thing so they can't update firmware in other phones like the iPhone to support it. I can't link to any articles from the XDA App but read any of the major Android blogs as they've been reporting about it for the past couple days or do a Google search for SVDO.

BAAMM! lol
That is the rumor Verizon is not using 1X advanced, so the only way that simultaneous voice and data works if you have two radios which are capable of transmitting at the same time. This is why only select 4G phones support SVDO.
As I said earlier, SVDO will work in both 4G and 3G areas because of the dual radios on-board.

The Thunderbolt have SVDO support, because it's using a SVDO capable chipset. Dual radios doesn't have anything to do with it, but only with CDMA/ 4G LTE handoffs, which is similar to Sprint's 4G phones. SVDO works on a 1X and 1X Advanced capable device, so didn't need to switch to 1X Advanced in order for it to work, though they have been some 1X advanced codecs for a while. Verizon wanted this including in their iPhone 4 phones so bad, but it just wasn't ready.

Ok, so I was interested in checking out the LTE speeds and wanted to test out the ability to do SVDO. I went to my local Verizon store and realized that My area doesn't have 4G yet. Duh! lol. And when inspecting the phone itself I could not find a way to turn on or any mention of LTE in any way anywhere on the phone! Hmmmm. So then I tried to test SVDO. I called one t-bolt with the other display t-bolt and then tried to surf. Newp. no can do. The call went thru so Its all setup but maybe it had no sim card?? I didn't check. Maybe my area doesn't have SVDO yet either? Can anyone now confirm simultaneous voice and data??? Now that people have got the phone in their hands now.
I am not in a 4G area and I can confirm the phone does voice and data simultaneously, very well, I might add

You know my verizon rep said a funny thing today when I asked him about the voice/data at the same time on 3G...he actually said "we don't guarantee that will work yet and that the network is still being worked on in some places to enable this feature for certain devices like the Thunderbolt" I had already tried it on the demo TB so I wasn't worried but maybe that's why it's not working for you.
I can also confirm that in a non 4g area it does both voice and data at the same time... nice feature I didn't expect.
Hmm, yeah I guess as usual my area is slow at upgrading the network. Man, if Verizon would pay my etf on Sprint I would be all over that thing.

I work for verizon and you are right they have changed on the network side making simultanious voice and data through both 4G and 3G and it was done on the network not on the phone itself. Now I don't know if this was the reason for the month and a half delay or not but makes sense. From what I heard from my friend in the testing department it had to do with battery.
I don't know about you guys but I really love the fact that all the naysayers that simultaneous voice and data is impossible can finally shut up. LOL

I'm sure there is a switch under the battery Criket<>Verizon ... I never got why you would pay 700 for a phone just to save 40 a month and not have 4g and have sub par service... but i'm sure someone will develop a criket rom like the did with the incredible but nothing special

Because after 10 months that 40 turns into 400 and we just paid for the subsidy that ppl are paying for every month for 24 months(40 * 24 = $960) In comparison, after 24 months you get paid $260 for using it on a different network. Sub par service is a matter of opinion...no need to be rude about it, some ppl prefer a frugal alternative.
I guess the thought is that you could buy a cheaper device, and get just as good performance out of it because on Cricket you will never, ever, see any of the 4G speeds that we see.
This thing gets downloads that are consistently as fast as my Home Comcast (15mbps). I have seen some speeds that are double 30+mbps.
I guess what the other poster is thinking is that you could buy a droid 2 or a droid X and basically get the same results. Outside of the 4G LTE speeds, this device is nothing more than a MT4G or Desire HD (same internals). You wouldn't have to spend the extra money for a 4G phone that you will never utilize.
I thought that cricket was signing up for Lightsquared's LTE service? Which I would assume would be the same 700 Mhz our devices run on? I could be wrong, but if cricket did this it seems like it wouldn't be a terrible deal and as op said, he would still save money and actually be able to utilize the service. I doubt they would have the coverage we will, but don't denigrate the dude. He did nothing wrong asked a relevant question. Sorry, this was more directed at two_cents.
I have no idea what frequency Cricket would use, but keep in mind that metroPCS has 4G LTE as well and it is not at all compatible with Verizon 4G LTE. So it may be that the carriers try to distinguish themselves in the near future (especially from value based carriers) based on their phones not being compatible with other networks.
This would have the effect of making you go with one of the Big 3(?) carriers if you wanted a quality smartphone, or pick an inferior or entry level device and go with a prepaid carrier.
Yeah, I know metro's is different, but I was thinking that, which I could be remembering wrong, that LS's LTE service was going to be the same 700mhz. Like I said, I could be wrong. This is just what I vaguely remember.

Chips in Crickets?
Been an At&t user since forever. Service is good enough in Savannah and the job pays for it so I haven't had an argument to switch. So, SIM cards in phones have always been the norm. Could switch out my Nokia, Palm, iPhone whenever.
So forgive my ignorance when I ask what the significance of sims appearing in Cricket phones to being able to use the Thunderbolt? I currently use a Huawei on Cricket to play with and it doesn't have a sim. I've seen a Droid X also on Cricket and I don't know whether it has a sim or not.
Personally I wouldnt use a DX or TB on Cricket but for $55 a month (unlimited everything) it's an attractive offer.
Btw, the Huawei is Z4 rooted and has 2.2.1, which ruins the Wifi. But Wifi tethering works great. About 1mb u/d, but worthwhile. My iP4 gets 3+mb down and 1+mb up on 3G even with MyWi. When 4G LTE comes here with big red then I'll probably switch. I looking forward to a 4.3 screen and 2.3GB

I think you are mixing up Cricket for Metro PCS.
also the 700Mhz band is verizons if I am not mistaken, so the band will be different for Lightsquared's LTE unless them roam on verizons network.
No, I know metro has their own LTE service, that is not on the same bandwidth ours. Reading further into the lightsquared's frequency range they are on three bands. 1.4 1.6 and 2.0. So, yes I was wrong about it about the TB working on crickets network if they partnered with LS, but I wasn't talking about MPCS. I thought that I had saw where LS was running on the 700 mhz band with VZW. Not sure where I pulled that one out of thin air from, because apparently I was way off. Here's where I got my new info.http://www.dailywireless.org/2010/07/20/lightsquared-announces-lte-network/
MPCS runs on the 1700 mhz band.

Since no one has yet answer the original question... I'm a professional cell phone tech normally all Verizon phones can be flashed to cricket HOWEVER Verizon has decided to use identification cards similar to Sim cards for their service starting with the thunderbolt and all future Verizon 4g phones. I have yet to attempt to flash a thunderbolt I will try Monday however I'm fairly confident without the id card it will not work on cricket. The card is what stores registration info for the network now VERY similar to a Sim. I'm doubting a flash will work but I will repost tomorrow with my results.

Its possible because cricket will be getting 4G LTE sometime at the end of this year or early next. But it also depends if it works the same as Verizon's.

The thunderbolt having a sim card is for lte only and has nothing to do with being able to do data and voice at the same time when only on 3g. The thunderbolt utilizes svdo technology on verizons cdma network which allows voice and data simultaneously on a cdma network. Sprint is fully capable of implementing the same tech but will they is the magical question.
Never said the sim card allowed 3g n voice, its the reason it can LTE and voice. I followed that by stating Idk if it can do 3g n voice

why are people say the evo 3d cant/wont when the evo can?
The Thunderbolt can do simultaneous voice/data over 3G (SVDO). From what I've read it has one of the first qualcomm processors that allows this with CDMA.
http://forum.xda-developers.com/showthread.php?t=994994&highlight=svdo
http://www.howardforums.com/showthread.php/1695462-Svdo
I think the question is whether the Evo 3D's processor is SVDO-capable and also if Sprint/HTC also enabled SVDO through software. popular nobody can probably chime in with more insight.
I've also read that the Evo Shift's processor can do SVDO but it is not enabled for whatever reason.
Because the Evo can't. You might want to try that some time.

Not trying to be rude but what part of "while not on 4g" don't you understand?

The Thunderbolt can do simultaneous voice/data over 3G (SVDO). From what I've read it has one of the first qualcomm processors that allows this with CDMA.

I think the question is whether the Evo 3D's processor is SVDO-capable and also if Sprint/HTC also enabled SVDO through software. popular nobody can probably chime in with more insight.
I've also read that the Evo Shift's processor can do SVDO but it is not enabled for whatever reason.

It has to be supported on the network as well. With verizon, svdo isn't fully supported or available on their entire network but it is available in a lot of markets.

According to the Qualcomm slides from the howardforums link I posted "Simultaneous active 1X voice and EV-DO data, sometimes referred to as SVDO, is a new standard-independent device feature that significantly enhances the user experience without impacting the infrastructure side."
Sounds like the network has nothing to do with it.
i can talk and use the internet over wifi on my evo, but i know for sure it wont work over 3g.... thats okay though!

It still requires internal testing on the network side, but it's all software. Sprint have a few pre-production devices with the SVDO chipset included, but those devices will most likely be available when Network Vision is out. The EVO 3D doesn't include it at this time, and only the software is being worked on right now.

Well as many EVO users know there is a distinct possibility (probability) that Sprint will be getting out of the WiMax game at some point in the next couple of years and joining the LTE bandwagon. Of course, it's a simple switch to make on their end as it only requires a firmware update, however on the phone's end it is not quite that simple.
Has anyone heard anything about the possibility of the 3D having a dual mode chip? I would like to hang on to this next phone for a while and I'm hoping we won't be saddled with only 2.5 ghz spectrum wimax (the spectrum is also something I'm curious about with the former nextel bands' uncertain future).
Can you explain why Wimax is so bad.

Well it's spectrum isn't effective at structure penetration. Built up cities like NY have a lot of problems with getting signal on one block, then losing it the next "sort of thing". LTE's lower frequency would eliminate some of that issue.
I'm not saying it's bad, and I'm avoiding saying anything about LTE being faster because we need to give it time, once enough people load down the network, itll be a wrap.
Also, Sprint/Clearwire were testing a new format that utilized LTE/WiMax combined with a real world data throughput of somewhere around 70-80Mbs. Why would you not want that?

That's a very blunt way of phrasing the question but I'll do my best:
WiMax in and of itself is not necessarily "bad", but to sum it up, Clearwire (who Sprint has partnered with in its 4G endeavors) is pretty well tanking, and I believe that LTE is the superior standard if you base it solely on tech specs. Add to this the fact that LTE has become the de-facto standard via its adoption by ATT & VZW.
Other complicating factors are the fact that Sprint's 2.5 Ghz spectrum has well-known issues with building penetration, the fact that the 800Mhz former nextel spectrum would be a good candidate for rolling out LTE and having better service, the fact that LTE (supposedly) lends itself better to carrier control (ie not in favor of net neutrality) and probably some others, and the fact that sprint has itself said it is investigating the possibility of going LTE, it doesnt even really matter if WiMax is "bad" because it's probably going to happen one way or another.
Wimax 2 might hold promise but I honestly am already over my head here and I'm saying I don't want to be stuck with a phone that overtly clashes with Sprint's 4G vision of the future.

Just to clarify, I believe Wimax actually isn't the problem, if it were deployed on a lower spectrum it would have comparable signal penetration.
IF sprint switches to lte (hope not) then it won't be soon enough to worry about with the evo 3d, you will undoubtably upgrade your phone in that time, unless you can withhold the temptation to buy quadcore superphones next year
Project leapfrog is in the works for sprint. Meaning, they're coonverting to LTE by 2013. Which, in theory, means the Evo 3D will NOT have LTE capabilities because it'll be most likely another year or two before you start seeing LTE on Sprints network.

Wimax is more efficient than LTE, it's the spectrum they are using that is hurting them. I doubt it will be but the Evo was the first 4G phone out so it would make sense. Even if it's unused when the phone is released.
The Evo is ready for Wimax2 (real 4G) and I don't think the standard hasn't even been finalized yet.
Can anyone explain why Sprint is expanding it's Wimax offering if they are going to be changing it in 2 years?

Interesting read sort of gives some insight about what Sprint may be angling for. If the problem with Wimax is the frequency that sprint is using, perhaps their acquiring new frequencies fixes the problem?
lte
Sprint was already testing lte in phoenix . They also dont need to aquire any new frequency as they are getting rid of the iden - nextel really soon and will probably use that as wimax or lte if they choose it . Iden was in the 700 mhz range and will give a much better coverage
I somewhat doubt they'd do 700mhz WiMax. The reason I say that is because WiMax is an IEEE standard, specifically 802.16m, and they specified profiles at 2.3ghz, 2.5ghz, and 3.5ghz.
Clear isn't there just to provide services to sprint, Clear is there to be a broadband provider. That said, they're going to be working with devices that follow the IEEE spec.
It's possible they'd do 700mhz, but unlikely.

Sprint doesn't have anything in the 700MHz area last I checked. They didn't win the auction when it was held.
sprint has 806 MHz to 824 MHz and 851 MHz to 869 MHz bands. http://www.accedian.com/blog/news/sprint-vacated-iden-spectrum/
"There is no uniform global licensed spectrum for WiMAX, however the WiMAX Forum has published three licensed spectrum profiles: 2.3 GHz, 2.5 GHz and 3.5 GHz, in an effort to drive standardisation and decrease cost." -per http://en.wikipedia.org/wiki/WiMAX
Regardless of what they own you are right in that Spring/Clearwire cant just wake up and decide to deploy WiMax on a lower Freq that they own b/c at this point in time its flat out not provisioned for it. However I have no clue as to how hard/easy it would be to get such a provision so anything is possible.
The thing with LTE is its provisioned across all freq bands defined for UMTS, which typically consist of 800MHz, 900MHz, 1800MHz, 1900MHz. per http://www.pixaware.com/LTE and WiMAX Comparison-TejasBhandare.pdf
I personally speculate that they will go the dual route b/c WiMax has its advantages over LTE in its own areas.
I understand that but I know that clear does what sprint says since they own more than 50% . Sprint will do something with the band width that nextel was using and it looks like the test in phoenix was good. I would not think they would go dual but its only software its easy to go from wimax to lte and so forth but I think it would send the wrong message if they did it . Should be interesting whatever they do . But I bet they use the nextel bandwidth to implement lte

you said LTE is being adopted by att and verizon...its actually ONLY being taken by verizon. att is hspa+, just like tmobile. and hspa+24 is faster than LTE actually, and that will be rolling out in less than a year. so LTE isnt the best.
I was saying that lte was better than wimax . They tested it in phoenix and got over 70 mbps . But some say wimax 2 is coming and such . It is never ending just like fios and cable . It will always be a search for speed . But right now you can google sprint and lte test in phoenix . may be the way they are going

Yea but by the time they roll that out, they will probably be working on upgrades to lte. It will be a never ending battle. Someone is always gonna have the upper hand for half a year.

Sprint isn't doing anything. They don't have a 4g network. They lease it from clear (they are majority owners).
i agree with what others have said, the problem with clear's wimax network is the 2.5Ghz spectrum it runs on.
Wimax is open source, it's theoretically cheaper to build than LTE, but i haven't heard of clear expanding the coverage fast as verizon and tmobile.
Here's to all of you The EVO 3D might have compatability woe Wimax R2 or the 802e/m which will destroy LTE in speed and No Sprint will not switch over its to much money

I have LTE, yea and it is as flaky if not more or less than wimax, trust me I was just browsing the 3d forums to see when it will be released or so and the rumors.
AT home I get constant dropouts in LTE, hell I cant even get a constant signal, and walk 100 meters out in the open and I get great LTE coverage. While I have a laptop with built in wimax module and I got free thirty days and I get a constant connection and great coverage. I have never lost connection.
LTE is faster but seriously after 3mb down it all becomes pointless unless you are using your phone for home internet and need a lot of traffic, for a phone a connection at 2-3mb constant is plenty fast.
My wimax module gets me 3-5mb consistently at my house, I have never seen it go below.

I doubt the OP will keep his phone for the rest of his life and neither are you so who cares if we have wimax phones now. Its called progress and lets face it when was the last time you heard anything about new wimax deployment? It seems like its every week to every other week you hear verizon expanding coverage or adding new cities that now have 4g. Sprint gambled and it didn't quite work out as expected so who cares at this point as long as there is something positive to look forward to in the future.

This means absolutely nothing.( i guess not absolutely nothing but its not the end all solution)
Just b/c they likely get LTE doesn't make it better at all than WiMax.
Those uneducated in the matter should take some time to read up some around here and the web and you'll learn that the reason WiMax in its current state with Sprint/Clearwire is the way it is b/c of a few things, one being the power the units use to get signal(hence wimax modems get better signal b/c they not running on battery like us) and the freq WiMax is placed on.
If they were to take LTE and swap out WiMax on the same freq we would all have the same issues as we do today, end of story.
We really need to understand that its not LTE vs WiMax its more about how the tech is implemented and such. VZ gets better coverage b/c its LTE is sitting on 700MHz channels so the building penetration is much better than the freq sprint/clear use 2.5GHz.
4G will get 10x better in the future once sprints network upgrade is rolled out and they have time to improve it. many options for them wether it be dual LTE/WiMax, or straight WiMax but using wider channel bandwidth and lower frequency. whatever it is it will get better, BUT it wont be just b/c its LTE or WiMax, itll be because of how its implemented.
also its been reported that this deal was done awhile ago. Sprint just reported earnings so its in there too now is all.

If they don't repurpose their iDen 800mHz frequencies to LTE then it really doesn't matter, it'll still suck hard if not harder. I think WiMax is the better protocol... Why not also transmit WiMax on the iDen frequencies instead? That would kick ass.

WiMax isn't provisioned for the lower freq at this time, unlike LTE. Dunno why this is or how that happened but it would take tests and FCC approval to put it on lower freq from what ive read.

WiMax is a simple protocol, basically just like your Wifi Router with Mac Access Control On on a different frequency.... Now there is nothing wrong with the 2496 - 2696 Mhz ban Clear uses except for the way Clear has laid it out, the wattage power Clears Towers are using and limited towers, back in the day the same exact frequency was used for Wireless Cable, MMDS can work from site to site for miles with excellent signal with only one tower center at the World Trade Center. Lots of compnies use LDS/MMDS to broadcast site to site data communications.
Unfortunately all these clear devices/sprint devices have small gain antennas which really hurt its ability to get inside large buildings.. The iDen Public Safety band would be an awesome idea, but I highly doubt you would ever see that happen as the Direct Connect feature is still highly used here in America and also in other countries and they all operate on the same frequency. If Sprint Nextel wasnt in such a $$$$ crunch, you would have seen a huge iDen network across the world. But I agree with you that sprint should use that band for data .. would be very interesting..

they did have GPS problems but the deal states that they are allowed to test their LTE on sprints network spectrum which will eliminate their issue evidently. Also allows lightsquare to roam on sprints 3G network and gives sprint the option to buy 50% of lightsquares 4g lte network if they want in the future...
Obviously yall didnt read much when it says CLEARLY its for capacity, and MAYBE future use if needed... smh, you guys think were gonna get off scott free straight to LTE, not a chance... the design goes like this... Agreement between LS and sprint for LS to deploy 4g LTE over "sprint spectrum" with 3g roaming.... Sprint gains access to 4g lte for capacity and possible future deployment if needed with satellite spectrum buying access, if LS decides to sell Lband spectrum. this gives sprint cash (8 bill) and the agreement is like 15 years.... this about sums up that article.

I'm pretty sure Sprint is phasing out Nextel. I work IT for our city and our Public Safety officers all use Nextel phones. Over the past 6 months or so, call quality on these phones has gone to complete ****. We are slowly moving our users over to Sprint phones. Most don't use the Direct Connect feature, but a couple have complained about losing it.
