does the cingular rom for the 8525 include Push To Talk?? If so, is it in the extended rom as a cab file?
No PTT in the initial release. I'm (just) now hearing that Cingular's PTT feature will be 3G based. It will be included in a subsequent 8525 update. No doubt, this will be tied in part to general 3G availability on Cingular's network.

By all early estimates you WON'T be able to use PTT on 8125, as it will be leveraging the Cingular 3G network...

there should be a way to fix that somehow.. just need to play with it... all of the "regular" phones that have PTT are not using the umts network.. i believe its all on edge.. anything could be possible.. im sure that if i cant figure it out that someone is bound to be able to figure out.. there is a smart bunch on here

That's one of the dumbest damned things I have ever heard.
Cingular's PTT only uses data to get the "buddy list" the rest travels as voice.
The phone knows no difference wap.cingular is wap.cingular regardless of the data, and with as small as the footprint is for 3G you would only be able to use it in about 10% of Cingular's coverage area which doesn't seem too good for a hyped feature.

Interesting observation ... but then in a 3G network .. the voice is also over WCDMA and hence much better quality .. and reduce the load on the GSM network ..

regardless of that... the regular "dumb" phones with the PTT feature do not utilize a 3G network... i guess the only way to really settle this is to get it and play with it on my 8125... im willing to try and i know a few others are as well... doesnt hurt to try, either we can make it work or we cant... no use in quivling over something that hasnt been released yet..... why dont we all agree to just wait and see what happens?!?

What makes you even think that PTT will be supported on WAP.CINGULAR? Cingular will be selling the 8525 as a premium device highlighting their 3G capabilities. There is also a strong likelihood that this phone (when sold) will be offered with PDAConnect (generally using ISP.CINGULAR) and not with a Media Net plan...

i have the old school unlimited media net plan for $20 a month.. and i can use both connection, wap.cingular and isp.cingular on my 8125, and so can everyone else i know with no extra data charges... if you ask me people with pda connect are getting ripped off since its so much more expensive

Cingular is not going to change their entire PTT setup over this phone. All the phones that use PTT use wap.cingular to get it. It may be accessable through isp.cingular as well, never really cared engough to provision someone only with isp.cingular for anything to find out.
Also on a 3G network, the voice is not transmitted over UMTS through Cingular. That will be implemented late next year. Until then UMTS is used for data only. Cingular doesn't want to flood the system with VOIP as well as excessive data use.
Drive from a 3G market to a non 3G area while on the same call. When you lose 3G you will not drop the call. With UMTS you cannot handoff from 3G to GSM on a call.
This is why PTT isn't operational yet: not enough 3G coverage. It's going to be a 3G only feature I'm afraid.
why do you all figure its going to be based on 3G? Cingular currently does not even offer any phone that is 3G and PTT capable (granted there is only 2 listed on the cingular premier site)... they arent even all EDGE.. all the ones i have seen are all EDGE except the SE Z525a .... the PTT only uses the internet to grab the buddy list, the rest is done over the gsm voice transmission same as a 3g network
actually, its not. 3G voice is WCDMA. That's why simulaneous voice/data can occur on a 3G network. Here's a great post from RF9 on HoFo explaining the differences between WCDMA and GSM.
EDGE/GRPS is an overlay of GSM (a TDMA technology.)
HSDPA/UMTS is on W-CDMA (a CDMA technology.)
W-CDMA and GSM are completely different networks and technologies.
W-CDMA is more like Sprint & Verizon's CDMA (or more like an improved version) but obviously not the same thing (and not compatible.)
W-CDMA is intended to replace GSM eventually and is being built out as a new totally separate network. So 3G phones basically have two radio devices in them, a W-CDMA and a GSM. So when W-CDMA is not in range, you fall back to GSM.
Separate radio networks that they are, they are glued together on the back end making hand offs from W-CDMA to GSM seamless.

3G phones such as the TyTN have two completely different networking technologies in them you see. Each network handles both voice and data.

[email protected] it, i forgot about that... And that is the only feasible answer on why it might not be possible.. except i doubt cingular is only going to make it work in a 3G area since its coverage is so small... but i guess we will have to wait and see what happens.....
PTT and 3G
I admit I really don't know how PTT works. But I would think that they'd be able to get it to work with both GSM and W-CDMA on the same phone. W-CDMA an GSM are separate air interfaces, but at some point it all glues in to the same network, which is why a call can hand off from W-CDMA to GSM.
But I'm sure it's not trivial, and PTT is a totally different animal since it's really VOIP if I understand correctly.
Here's an interesting post from Howard Forums from kribo20
http://www.howardforums.com/showthread.php?p=7974811#post7974811
This is the line of interest: "• All of the capabilities of a phone with Push-to-Talk (service will require a software upgrade in 2007), camera (Cingular 8525) or no camera (Cingular 8500) and many accessories"
So it appears that, according to Cingular University, the plan is to release it with PTT broken and make you upgrade it.

While I have no confirmation either way, I'm told otherwise. I'm told you can "soft hand-off" from UMTS to GSM, but not GSM to UMTS. Once you hadn off to GSM, you can only return to UMTS once your call is complete (the next call can be back on UMTS)
But I'm just telling you what the Cingular people told me.
(Just for reference for other readers HSDPA/UMTS=W-CDMA if I'm using too many terms.)

You really got beat with the stupid stick didn't you? PTT has been available for almost a year and it yet to be available on any 3G phones.
Please do some research (i.e. go to Cingular.com) before typing any further responses.

I've been employed with the company over 3 years, I am one of the few that have a clue as to what is going on within the company. You cannot handoff from one tech to another, just like with GSM-TDMA. Currently however 3G is for data only and voice still falls back on GSM and honestly I don't think it will ever really change because Cingular does not plan on extending it's 3G footprint much outside of metropolitan areas. By mid-2007 you will see where 3G is and where it isn't and it won't change much from that.
@decepticon: your etiquette is indeed fascinating. Your Mom obviously didn't teach you the basics. Or, perhaps she will cover this more with you as you get older.
Speaking of the word "cover", I'll cover your opinion in 2007 when the 3G PTT service is released by Cingular, the company you perport to work for. I'm finished with this thread FTTB. You might want to google WCDMA-GSM handoffs as its received a lot of coverage since it was first accomplished back in 2001. In fact, this technology is fundamental to WCDMA rollouts throughout the world for obvious reasons.

You're right, I just lie and say I work for the company and they lie and deposit a check into my account every 2 weeks. Either way, there is no UMTS to GSM handoffs because there is no UMTS VOICE NETWORK YET as well as no such plans to change PTT to a 3G only feature as 3G will never have the footprint that GSM has.
I love how some people can just make things up and pass it off as fact. I would show the Powerpoint, PDF's, and other material I have that covers this but I would rather not break an NDA just to prove some douche online is wrong.
Hi,
at the moment my Radio version is 1.47.00.10. My signal is strong enough, but is there any radio version which positively highlight itself because of less battery consumption?
thanx,

Depends on too many factors which you've not supplied information on. Radio performance varies depending on your network, where you are (country) and coverage and you have not specified any info so people won't be able to help!
Besides, if you stay in good strong signal areas you will only see marginal (if any) differences in battery life by changing the radio. You'd be better off making sure you don't leave services you don't need running (like WiFi/BT/push email) or buying a bigger battery
Ok, thanx for the info. I live in Germany, in Dusseldorf, on Vodafone (DE) network. I'm sure that the coverage here is pretty good. Would that make sense to turn off 3g?

Yes - providing you do not need 3G data speeds or calling features AND your operator provides equally good GSM coverage. GSM (in a good signal area) generally consumes less power.
There is a good little bandswitch plugin for the today screen floating around which makes it easier to switch bands when 3G isn't needed but I can't remember it's name so you will need to do a search in the general Hermes forum...
In terms of your original exploration of a good radio for your network in Germany, it would also be worth looking at the (updated) wiki here and in the last column you'll find links to the forum threads discussing peoples experience with each listed ROM. You don't need to read every post - just take a good selection of posts from the start, middle and end of the thread to get an idea. (first posts are always "wow" - last posts are always "I've got a problem...xxxx", middle posts usually sum up peoples usage after a few days/weeks etc.
If you do decide to test some radios - please play safe, understand what you're doing, use HardSPL (bung Oilipro a few €€€) and bear in mind some users have experienced irreversible hardware issues while using 1.5x.xx radios in Germany, Netherlands and UK so they may carry some risk but this is NOT fully confirmed but is being explored.
If it ain't broke and all that
Have fun!
hi
3G has come to India BSNL has launched it and to my knowledge the first test was at Chennai and is available at the metros
not at Bangalore but then bangalore is not a metro
can any one pls give more info on wat are the exact advantages on 3G mobile technology other than great internet experience and if every other mobile provider moves to this tec will we be able to use our existing phones??
Note : sorry if this is a waste of a thread i thought their mite be many like me who don't know and may be could get to know through this thread

3G -> Features (Source : http://www.m-indya.com/3g/3g_features.htm)
PACKET EVERYWHERE
With Third Generation (3G), the information is split into separate but related “packets” before being transmitted and reassembled at the receiving end. Packet switching is similar to a jigsaw puzzle- the image that the puzzle represents is divided into pieces at the manufacturing factory and put into a plastic bag. During transportation of the now boxed jigsaw from the factory to the end user, the pieces get jumbled up. When the recipient empties the bag with all the pieces, they are reassembled to form the original image. All the pieces are all related and fit together, but the way they are transported and assembled varies.
Packet switched data formats are much more common than their circuit switched counterparts. Other examples of packet-based data standards include TCP/IP, X.25, Frame Relay and Asynchronous Transfer Mode (ATM). As such, whilst packet switching is new to the GSM world, it is well established elsewhere. In the mobile world, CDPD (Cellular Digital Packet Data), PDCP (Personal Digital Cellular Packet), General Packet Radio Service (GPRS) and wireless X.25 technologies have been in operation for several years. X.25 is the international public access packet radio data network standard.
INTERNET EVERYWHERE
The World Wide Web is becoming the primary
communications interface- people access the Internet for entertainment and information collection, the intranet for accessing company information and connecting with colleagues and the extranet for accessing customers and suppliers. These are all derivatives of the World Wide Web aimed at connecting different communities of interest. There is a trend away from storing information locally in specific software packages on PCs to remotely on the Internet. When you want to check your schedule or contacts, instead of using a software package such as “Act!”, you go onto the Internet site such as a portal. Hence, web browsing is a very important application for packet data.
HIGH SPEED
Speeds of up to 2 Megabits per second (Mbps) are achievable with Third Generation (3G). The data transmission rates will depend upon the environment the call is being made in- it is only indoors and in stationary environments that these types of data rates will be available. For high mobility, data rates of 144 kbps are expected to be available- this is only about three times the speed of today’s fixed telecoms modems.
NEW APPLICATIONS, BETTER APPLICATIONS
Third Generation (3G) facilitates several new applications that have not previously been readily available over mobile networks due to the limitations in data transmission speeds. These applications range from Web Browsing to file transfer to Home Automation- the ability to remotely access and control in-house appliances and machines. Because of the bandwidth increase, these applications will be even more easily available with 3G than they were previously with interim technologies such as GPRS.
SERVICE ACCESS
To use Third Generation (3G), users specifically need:
A mobile phone or terminal that supports Third Generation (3G)
A subscription to a mobile telephone network that supports Third Generation (3G)
Use of Third Generation (3G) must be enabled for that user.Automatic access to the 3G may be allowed by some mobile network operators, others will charge a monthly subscription and require a specific opt-in to use the service as they do with other nonvoice mobile services
Knowledge of how to send and/ or receive Third Generation (3G) information using their specific model of mobile phone, including software and hardware configuration (this creates a customer service requirement)
A destination to send or receive information through Third Generation (3G). From day one, Third Generation (3G) users can access any web page or other Internet applications- providing an immediate critical mass of users.
These user requirements are not expected to change much for the meaningful use of 3G.

As far as i know our Gene does not have the capability for 3G services like HSDPA. We can have only GPRS and EDGE which are not very fast like 3G.

But who know with people like Krazy,ankit ,Ramersonw, addicted2XDA they might device a software to make it so ie if this capability can be given to us by ways of some kind a SW(i dont know cause im not a techi) im sure these guys will do it
who know may be in the future we might get a 3G enabled Gene anything is possible rite

As far as i know our Gene does not have the capability for 3G services like HSDPA. We can have only GPRS and EDGE which are not very fast like 3G.
For our dear tech crazies : Please correct me if i am wrong.

Its completely impossible to enable 3G on gene, as it is a hardware capability and not software.

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.
My apologies if this has already been asked, or if it is a complete newbie question... but with all the hype, "sightings," and now the "Official Launch" of the T-mobile LTE network in Las Vegas (which from what I can see, seem to be in Band 4 (2100/1700MHz)... What are the chances that if this launches in an area nearby that we might be able to get LTE speeds using the i717 with the stock AT&T radio? Anyone in the Vegas area seen / tried / tested this?
Don't think that's the case. They just refarmed the 1700/2100 band to the 1900 band. Meaning, they used band 1700/2100 for their HSPA+42 network. They now moved their HSPA+42 network (in Las Vegas) onto band 1900. They are preparing to launch LTE next year on band 1700/2100 which is why they are refarming their network. Right now,however, I don't think they have LTE active anywhere. Anyone can correct me if I'm wrong.

Well, I know for a fact the reason for this big push is so that people using iPhones on T-mobile will be able to enjoy higher-than-edge data rates on T-mobile... they've got a whole add campaign backing that up, too! I'm just hoping it can be beneficial to some of us using other AT&T phones on T-mobile... That would definitely make my day! :fingers-crossed:
That is true. The iPhone runs 3G on band 1900. So with this refarming of their network, people with unlocked iphones will be able to finally get 3G speed on t-mobile's network.

I don't see why you wouldn't. All LTE networks in Canada are AWS (Band 4) and its the same basic Note sold here. I believe mine went up to 30 Mbps real world when it was on Rogers LTE.
This tmob project "tmod" is in full swing across the country and going well. They are doing QA on a good chunk across the country as i type this. Even if you end up in an area waiting for fiber or a microwave hop (for your 4g) , you should be seeing better 3g signal as the sites are first maxed out for "capacity".
Real pain in the ass for the rest of us doing LTE for other customers,, cant get thru to my data center!
Good luck

Wow! Thanks for the info! I'm in the Seattle / Bellevue, WA area personally... hoping nothing slows down the infrastructure build up here... Would love to get higher speed data connection without the current radio hacks; just not sure if I'll ever be able to find out without constantly flashing back to the stock UCLF6 radio just to "test" every so often. Hoping if anyone out there sees it, they'll post here! :fingers-crossed:
For others who might be looking into this, there is a website out there to map "sightings" of new T-mobile 1900MHz network : www.airportal.de
Testing...
Ok... biting the bullet. Have a little extra time at lunch today, so I re-flashed my radio from the ICS-Blaze to the i717 latest UCLF6 radio, and removed all other mods I had in place..... Will drive to a few locations listed relatively near me on the link from the prior post, and see if I can't catch some of this elusive unicorn network testing goodness... Will report back! :fingers-crossed:
WOW!
Ok... so I did the testing. Annnnd...... SUCCESS! Though it wasn't quite that simple.... here's what I did:
With my reverted-to-stock radio, I drove to one of the flagged areas, and for about 5 minutes wandered around, with the phone seeing only a EDGE signal. Then I got to thinking that it might just not be prioritizing that protocol / type, so I went into the *#2263# service menu, selected WCDMA 1900, and literally, INSTANTLY got the high speed data link I was hoping for! Tried switching back to the "Automatic" mode, and it would still never intentionally switch to that service from EDGE, but forcing that frequency definitely worked, and with a very solid signal strength, and speed level. I did notice, however, that the network type seemed to be bouncing back and forth between UMTS:3 and HSPAP:15, for whatever that is worth. See the attached screenshots :victory:
One caveat, though... this is definitely only in 'testing' and very much localized, it seems. I tested the range, and it literally was only *that one tower* in the area serving that signal. I plotted the range and came up with a radius to pretty much prove it =(
Caveat aside, however.... I don't know about everyone else using the i717 on T-mobile, but this REALLY excites me Gives me hope that someday hopefully before too terribly long, I can stick rock-stock with radios on my Note, not worry about mods / etc, to only get relatively sketchy performance and occasional lock-ups...
BUMP'ing this cause LTE is officially out.
Anyone done any new tests or noticed anymore significant speed changes?
I pickled up LTE briefly a while ago getting on the highway on North Avenue in Chicago and THEN passing the same spot on the way back. Unlocked, rooted but stock i717. I also got some weird 50-70 upload speeds with regular (10-14) download speeds a bit before that; I don't know what that is. Here's the LTE-
