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

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

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.
Because the Evo can't. You might want to try that some time.

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.

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.

I keep seeing people post on a Development section saying Photon 4G with ICS or CWM or unlocked and etc, shouldn't we just call it Photon 3G and it's less confusing since currently we can't get WiMax w/ any of those method. I mean, it's already bad enough when we have marketing people calling, advertising, and forcing it down the consumer throat calling WiMax a 4G service when we all know darn well that is not what ITU want 4G to be call. And it's not like I don't appreciate the works that these chefs do, because I'm. But it kinda annoy the heck out of me when we know darn well as geeks calling these stuff 4G since we know there is no 4G, not even in marketing term.

That is exactly his point. Once the phone is unlocked, it is no longer 4G. Thus roms that break WIMAX (due to being unlocked) should not have 4G in the name.

The phone is called "Photon 4g". Consumer modifications to the phone don't change it's name. You are seriously just splitting hairs.
actually, I think the name is "photon" since motorola has put their trade mark after (and on) the "photon" instead of the "photon 4G".

with cellular (wimax)? I didnt know that was possible. awesome.
I guess one could argue that you are on another carrier (such as AT&T) with a USA gsm-unlocked photon and consider Hspa "4g." Although technically wimax and Hspa are not 4G, some carriers market it as such.
now that would be splitting hairs. :laugh:
4g hspa+, right?
Sent from my MOF'd up MoPho
I could be wrong since I'm not w/ t-mobile, but isn't its 4g apply to hspa+ and not hspa? I don't think photon support hspa+ either, maybe just hspa.
HSPA+ is officially defined as 3G release 7, and is not considered 4G by ITU-R even under a relaxed standard.
that being said, I would be thrilled to have those speeds regardless.
well it apparently DOES have an LTE chip inside as well as so-called Wi-"Max", but if that will ever be functional, who knows, but it does have "4G" capability, just not functioning ones, yet.
photon doesnt have LTE

OK - lesson learned for you I guess. Don't expect people who read and post on lots of boards to catch the little nuances of your (unstated) sarcasm. I skim numerous boards and posts everyday and also love sarcasm - and still get in trouble because someone reads me so very literally!
Peace to you!
Okay guys, simmer down...
On a less harsh note, why not call it an Electrify? The only difference between an Electrify and a Photon 4G is one has a WiMax chip and the other does not. If you have a WiMax chip, you have a Photon, but if your ROM can't access it, you might as well just call it an Electrify, since functionally, that is exactly what you have. A Sprint Motorola Electrify, since Electrify literally means "Photon 4G without 4G" (4G as WiMax, not trying to get into the nuances of what is and isn't 4G).
Meanwhile, Electrify users continue to have an Electrify because we have no WiMax to lose.
Also, the correct answer is: "Because that's the model name." 4G is part of the model name.
No sarcasm above this line.
Lastly, I wouldn't trust an iAnything to run to the store for me, let alone Android... Also, "Can" does not mean "Should". You can probably get ICS on an N1 or Desire, but should you? Absolutely not.
So, this may be an unrelated question, but what happens when Sprint switches over to LTE? I'm in LA (Pasadena, to be exact), and sometimes it seems like the promised "4G"-speeds never appeared. I almost switched over to Verizon until Sprint offered me a refurbished Photon in place of yet a 4th replacement Epic 4G.
Sadly, now that I really have fallen for the Photon--I've always thought Motorola makes great phones (but succumbed to the Epic's promised keyboard awesomeness), I'm wondering how long Sprint will support WiMax.
[Sarcasm]Maybe I should switch to the iPhone 5 when they come, at least there's only one party line./[Sarcasm]
I've been with Sprint for 12 years and it has always been that you couldn't have data and voice at the same time with their system unless you were on the 4G connection. What changed with the EVO, I now have a data connection when I am talking. I can surf the net, emails come through, everything just like I have a 4G connection. I'm in Portland and we don't have LTE here so I know that's not it. I'm not complaining just curious.
It's called SVDO, simultaneous voice over data. Separate chips allow for this.
Well-known feature, but not well-publicized. The upgraded towers will allow SVDO on newer phones.

It was my understanding it was a combination of both. I find it difficult to imagine that Sprint could've had SVDO for years if only phone manufacturers supported it.

Not quite true, did you know that the iphone 5 on sprint/verizon can't do voice and data at the same time even while on lte? Also, did you know that the evo lte, gs3, viper 4g can also do voice and data simultaneously over 3g and not just lte? Like someone else said, its called svdo. Not every lte phone is capable of svdo but there are a few that are and what determines svdo capabilities is the chip/radio design in the phone and not on the network side.

So, if possible, why wouldn't Apple install the chip/radio possible of doing simultaneous voice and data on the Verizon and Sprint versions of all the iPhones since they did on all of the AT&T versions? Seems like a no-brainer for Apple to do that, and make their iPhone stand out amongst all other phones. Also, why only do it for AT&T versions and not Sprint and Verizon? Just seems like a stupid business/marketing decision Apple made, if it is possible and they just chose not to...
Also, so the GS3 can do simultaneous voice and data over 3G on all of the carriers that it's offered on? That's very interesting, because I had no idea! I thought that it was something only possible on newer Android phones when connected to LTE. I have never known that it has been possible for a while on Android with the right chip/radio. Why wouldn't manufacturers do this sooner!? Why did multiple manufacturers suddenly decide to do this to their phones around the same time? Just seems crazy to me! If I was HTC, I would have been putting this chip/radio in for a while now, as something to make them stand out against other Android phones! Seems like a very obvious marketing strategy!!

Also, so the GS3 can do simultaneous voice and data over 3G on all of the carriers that it's offered on? That's very interesting, because I had no idea! I thought that it was something only possible on newer Android phones when connected to LTE. I have never known that it has been possible for a while on Android with the right chip/radio. Why wouldn't manufacturers do this sooner!? Why did multiple manufacturers suddenly decide to do this to their phones around the same time? Just seems crazy to me! If I was HTC, I would have been putting this chip/radio in for a while now, as something to make them stand out against other Android phones! Seems like a very obvious marketing strategy!!

The iphone on att has been able to talk and surf at the same time because thats how gsm works. For a cdma phone to do talk and surf at the same time u need a dedicated internet source or an svdo radio installed in the phone. My guess is apples proprietary hw wouldnt work with an svdo radio on sprint/verizon. Or they just simply didnt want to include it.

Cool. Thanks. Yea, I knew that the iphone on AT&T has been capable of this for a while now. I thought that all GSM networks were capable of this. After reading themuffinman's post, I thought he was saying that it was all up to the phone itself and didn't rely on the network at all. That would mean that a GSM network wasn't always capable of doing this, but if the phone was capable THEN it was possible. After reading your post, then re-reading his post; I think what he was saying is that CDMA networks couldn't do this if the phone isn't made capable, and not that GSM networks couldn't if the phone wasn't capable. Now that makes sense to me, and is how I've always thought that it worked.

Because the Qualcomm chip that enables svdo on cdma networks wasn't out yet. It made its first appearance on the LG Viper 4G. Once the chip became available only then could manufacturers add it on. Like Evo lte and GS3. You see how Samsung decided to go with their Exynos quadcore in the Note 2 and because of it unlike the S3 we have no svdo.

I forget who but I just laugh at the one who doesn't understand why apple wouldn't do it for all phones, its bad marketing.
HELLO its apple after all lol
Not being mean, please don't take it that way, just saying
RootBox EVO LTE 4.2 Baby!
IMO it's because apple likes to leave things out so they can put them in the next version. That way they can tout it as a 'new' feature (new to them at least) and the sheep will buy in.
Remember how the original Iphone didn't have 3g?

This probably wasn't so much an Apple decision as it was an AT&T decision. AT&T has been hit hard ever since they lost the iPhone exclusivity in the states, they want to milk it for all its worth. Apple doesn't do the "leave a feature out" bit on purpose.
The original iPhone did not have 3G because 3G wasn't nearly as ubiquitous as it is now. Well, I say "as it is now" but then I look at my phone right now and I see that I'm on 1X anyway. Not many people even realize that when the first iPhone came out, smartphones weren't seen as the multi-purpose machines that they are now. Hell, the first few revisions of iOS weren't even designed with the idea of third-party apps at all. We've come a long way since then.
We could also be called "sheep" as well, you know, we keep buying into more and more powerful Android phones with insane processors and ridiculous GPUs but it wasn't until Android 4.2 that the UI is as consistently 60FPS-smooth as an iPhone that has half (if not less) the processing power. Just saying, you should keep an open unbiased mind, that's what separates you from the fanboy-lusting Android people who froth at the mouth when Apple is mentioned and mature, logical, and reasonable adults. (not accusing anyone of the former)
Afaik all iPhones are identical internally across all carriers regardless of gsm/cdma...only reason a att iPhone won't work on sprint is bc sprint won't allow it ...they won't even allow an unlocked phone on the network even though it is perfectly capable of it ..

Well, due to the nature of CDMA and ESNs, you can't actually "unlock" a CDMA phone (unless someone would like to correct me).

Not entirely true there.... Chips were out that could support it before the Viper...
Hence the Thunderbolt had it with the addition of an extra modem on board on the MDM9600, which was used for evdo data, and let the MSM8655 handle the 1x cdma voice connection....bringing you svdo... Now sprint had no need for the extra MDM chip like Verizon did back then as its main purpose was for LTE connectivity... Not worth adding the extra modem back then just for svdo...
