I am curious if it is the hardware or software that allows you to get the "21mpbs" download? I know the original vibrant was "7.2mbps".
It is the hardware...
Damn them.
Thank you!
What do you need 21 MB for on a phone? Unless you are tethering? ??

I took one apart (a S4G) and they are exactly the same inside unless the actual board is different, my guess we will be able to create a patch that will increase our current speed probably 1.5 faster, on WIFI my phone does 19 mb down and 5.8 up so the current configuration is good enough to to handle the speed.
Would you have to update your data plan for this to work?

So is the answer yes, no or don't know?
I heard you just have to upgrade data plan on tmo website.
upgrading your plan doesnt do anything. It's just a way to merge all plans under the "4G data plans". You WONT get 4G speeds for switching. The 4G speed comes from the different radio in the Galaxy S 4G that the vibrant doesnt have. Its a hardware thing, not software. /thread.
No, it is different modem hardware. Vib 3G is Infineon cellular modem. Vib 4G is ST-Ericson modem.
You don't need to do anything to your data plan, just get a Vib 4G phone.
Unfortunately you cannot get 4G speeds on the Vibrant...even if you choose the "Android 4G plan" from T-Mobile. It is only a label and makes no difference within the phone itself. The Vibrant 4G has a newer radio that can work with true 4G, but sadly the highest we can go is 3.5G lol
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 believe it's impossible. At best, all you'll be able to do is voice and nothing more. No data at all, whether 3G or 4G. Network authentication is done differently on an LTE device. They will ask you for an ESN number, which you will not be able to find anywhere on the device.

Eh, not entirely true. I checked out the carrier and it's sprint's cdma network so he should get voice and 3g data fine. Obviously won't be getting anything above 3g speeds though.
speeds though
To the OP if you are really motivated to do it, I would read this as it shows how others have done it for the thunderbolt.

Sprint doesn't use a compatible data network authentication scheme as Verizon, so no, he will have no data service unless he can find a ROM for the Tbolt specifically ported from a Sprint device. It's well known that Sprint devices such as the EVO line don't work on Verizon, and that Verizon devices such as the dInc and dInc2 will not work on Sprint. I've worked with both.

It's easy enough to look up. Search the dInc forums. I know there's several threads there addressing this issue. I'd be surprised if the EVO 4G forum didn't have a few too, and I know there's at least 1 or 2 in the Tbolt forum that address this issue as well; a fact I considered pointing out to the OP. Furthermore, Tbolts don't have ESN numbers. They interface with both the 3G and 4G protocols differently than standard CDMA devices.
http://forum.xda-developers.com/showthread.php?t=1138411
This kinda explains what I'm saying. If you can't do it with a straight CDMA device without a world-class hassle, it's functionally impossible with a Tbolt.

Yeah, perhaps not with sprint's network (after reading), but certain networks seem to work like Metro's. If the OP has to ask though, he probably doesn't have the will/determination to persist on doing whatever it takes though. He'd be better off getting something like a nexus s for sprint and use it on boost or an evo of some sort.
Yeah I was just confused weather I will be able to read the esn and MEID locations. Right now I have Dinc with Boost mobile, mms, data, sms and voice all working.
But now I want the Thunderbolt and because it uses a Sim card I wasn't entirely sure.

Recently, I called VZW inquiring about my new tablet (xoom) and wanted to get the unlimited data plan applied to the tablet since I already pay for unlimited data on my main line and tethering. (Yes, I know I don't have to pay for tethering, but I figured 54 bucks a month for unlimited 4G as a home service and cell is fair). In any case, VZW informed me that I'd have to buy a package for the tablet, which I attempted to argue that if I pay for the hotspot, why can't the XOOM have unlimited.
In any case, here are a few questions/thoughts I had. When the Thunderbolt is connected to the 4G network, what happens with the CDMA/EvDo portion of the phone? Is it still being used, or is there a possibility of me changing the MEID on the tablet to trick the network? I've noticed that the thunderbolt (if I'm wrong, correct me) actually has two radios and uses them in different ways-
Radio 1 for 3G Voice Radio 2 for 3G Data
Radio 1 for 4G Voice/Data Radio 2 Off (Verify???)
Radio 1 for EvDo Voice Radio 2 for EvDo Data
Or some sort of combination of those. Maybe I have some sort of misconception of how exactly this phone works, but I'm curious if it'd work keeping the SIM in the thunderbolt and modifying the 3G Xoom to use the phones MEID. Does anyone have any sort of insight on to this?
Thanks!
4G is for data only at this point
Sent from my ADR6400L using XDA App
But see... I don't need the 3G data then... Would it work if I used the 3G just for data?
The Tbolt has 2 radios. One is the cdma radio built onto every msm8655, the other is the MDM9600 which includes both cdma and LTE radios. All data is handled on the MDM9600. The cdma radio on the msm8655 runs only 1xRTT CDMA for voice and sms text. Authentication for the MDM9600 is handled via the SIM card, unlike other devices where the cdma authentication is handled conventionally. Unless you can rewrite a SIM card, I'd say this would be pretty hard.
You could tether the Thunderbolt to the Xoom. Then you don't need an extra data plan at all.

I wondered why the OP didn't consider this a valid option as well. I suppose he/she just doesn't want to have to carry the Tbolt around and worry about it's battery as well. :shrug:
Any one know of a way to force the atrix to stay on 2g. I have tried the switch Widgets, in settings, selecting GSM network, and entering the *#*# stuff. I have 2 of these phones. One rooted and one is not. Neither will work. Any thoughts?
Thanks.

I was gonna suggest that you move to a remote area like Alaska... I see that you've already tried that.
I can get mine to switch in the network settings, but after a while it always goes back. I'd like to know the answer as well.
That was the first one I tried. LOL.
But honestly that's why I want to do this, because 3g network isn't the best here.
I might be as good with carrier pigeons, or better yet eagles.
Thanks for the thought.
What rom are you using?
In CM7 there is an option, but I don't know if its in the stock rom.
Wireless & Networks -> Mobile networks -> Use only 2G
In my experience, you have to have an unlocked and a rooted phone. Using clockwork mod, you have to load a different radio rom. I used N_01.100.00R_gb_retail_22sept2011.zip. But my atrix is on att. I believe att's radio roms are locking us out of the feature to manually switch bands.
Same here at&t atrix using n 0.100.00r
And in alaska

I've tried cm7 and other roms, build prop tweaks, etc... I thought it was the network, but several of my other phones switch over just fine. I have 2 atrix phones, one bootloader unlocked, rooted etc.... the other is factory, brand new. They both do the same.

Flashed this radio, and can now switch band with no problems.....n 0.100.00r
Android services menu (be careful) on froyo and ginger bread stock roms, Dial *#*#4636#*#* Here you will find a setting to change bands. Make sure you note the default (cdma/prl something, something) . The terminology would make you think Verizon (cdma) but that is not what cdma, means in this context, means. However gsm, in this context, does mean 2g. Cdma means "prefer 3g and drop down to 2g".prl means "preferred roaming list" which does not mean roaming, but what are the nearby towers to flip flop between. Anyway, this is all from memory and am hoping this is enough to address you request.
or look under settings (if not running stock), data, and 2g is there, as devs have enabled this in the native user ui.
