So I ordered a new, sealed I9020A from eBay. Arrived today (I'm out of town) and my wife took a photo of the box. It's a model GT-I9020FSRRWC, which is a Canadian variant of the Nexus S with compatible US 3G bands (AT&T). Here is my question:
I have had several I9020A's in the past here in the US. All had horribly slow 3G data and I returned all three of them because of this. Now, I know that Best Buy is subsidizing an I9020A variant for AT&T, making the model "sanctioned" on AT&T. I have to believe the radio & firmware for that model works seamlessly with AT&T's network (which the Canadian I9020A's don't). I know I can flash the radio from KB1 to KB3 or something similar, but would applying the firmware for the following make it identical to what Best Buy is selling as the official AT&T variant?
GTJ61 - Android 2.3.4, the original Nexus S firmware for the US version of I9020A.
From here: http://forum.xda-developers.com/showthread.php?t=1063664
Basically, I want the identical firmware and radio as the units sold for AT&T by Best Buy on my Canadian device because I don't want to deal with any network funkiness. It's maddeningly frustrating...
Thanks.
I've tried the new AT&T modem, it's still speed hobbled. For some reason, all modems that come with the i9020a have a capped transfer rate. I've flashed the KB3 radio from the i9020T series and i can now easily reach over 2 megs on the upload.
the KB3 modem also deadens the search button bug a lot.
Hmm, not the news I had hoped for. I'll give it a shot...thanks.

So does anyone know the difference between the GT-I9020A and GT-I9020FSRRWC?
Thanks!
use the HSPA build.prop tweaks from the radio thread http://forum.xda-developers.com/showthread.php?t=1116884 with KF1 radio you should have normal speeds so long as its not a hardware issue

Okay so I couldn't help but notice BestBuy no longer sells The Nexus S for T-mobile anymore, but what I did notice is they do sell it for At&t with the i9020T Model Number Attached leading me to suspect that this phone does have the hardware capability to run 850/900/1800/1900 as well as 900/2100/1700 network bands, it is software determined which also makes total sense with the possible inquisition of t-mobile by at&t which I might add may still happen. Whats your thoughts people?

Not correct. Different radios on the chip.

It's definitely not software determined. If they sell the T version to an AT&T customer, they will definitely be giving the customer a new phone when they find out 3G doesn't work.

And can you please show me your sources of information, or are you just passing on something you read?....you do know the i9020A is no longer available, and t-mobile contracts for nexus s no longer exist, only at&t and sprint have it now at&t version now branded i9020T,
GT-i9020T is actually a quad band model however they only previously enabled T-Mobile 3G the hardware itself can handle the frequencies, it would however need the baseband flashed via ota update from the manufacturer for the baseband radio to be enabled for at&t 3g , I think a little surprise will be awaiting once the ice cream sandwich ota update arives baseband update included....

Yes, it is quad band 850/900/1800/1900 on GSM. It supports HSPA frequencies 900/1700/2100. That is not 3G compatible with AT&T.
I just got a Nexus S from Best Buy for ATT and mine is a A not a T.

So I have a Nexus s that I got from best buy for AT&T and I recently dropped AT&T for T mobile. I'm trying to update my nexus to 4.1 and I keep getting the status 7 error. My version was and still is I9020A and that's the update version I tried. Do I need to use the T mobile one even though its different? Just trying not to brick my phone. Sorry if this is a little confusing. Sorta new to this.
Thanks!
The rom for the i9020A is the same rom for the i9020T. You are getting that error because your Clockworkmod recovery is old, update it.
You can also flash the factory image from here: https://developers.google.com/android/nexus/images
Please let us know if you get 3G on Tmobile with it and what area you're in.

The radio is the only difference. I9020A runs on 850/1900 while I9020T runs on 900/1700/2100.
So you won't get HSPA on your phone, only EDGE if you have I9020A on T-Mobile.

Actually at some location T-Mobile sim works with 1900 band now, due to the deal after the failed buyout by ATT. I got 3G on T-Mobile using an unlocked Captivate.
Hi,
Blaze 4G is one of the few phone whose radio supports both AWS and PCS bands (1700/2100 and 1900, respectively). Currently, I am using AT&T network with StraightTalk (PCS band). Here is my question, will new modem version for this phone support the same UMTS frequency bands as the original one? There is a new UVLH5 radio available for ICS. What is practical difference between UVLB7 and UVLH5? I really need my phone to support American PCS, AWS as well as European IMT, as I use my phone there too.
Thanks!
Well, seems like the new UVLH5 modem support same frequency bands as the original one. I tried swapping AT&T sim with T-mobile sim, and they both worked fine (HSPA). I still do not know what is different between the old and new modems - I did not notice any difference. BTW, new ICS modem works fine with GB rom.

i've noticed this as well. they seem completey cross compatable and i havent actually noticed ANY difference at all between any of the 3 versions.
im also using mine on straight talk, att sim, and it work great. maybe even better then the at&t moto atrix i have on straight talks att sim.
as for working in europe, i couldnt say, but if you are willing to provide the plane tickets i will gladly fly over there with my blaze and check for you.
They fixed 911 and call echo issues between the first two, as for the uvlh5 it was just minor bug fixes. I was wondering myself if there was any way to use the radios in the t989 list. They can use ours, so shouldn't it go both ways?
Hi All,
I have a GT-I5801 that I received as a gift from relatives. It was purchased in Hong Kong,
Baseband version: I5801ZHJP3
The phone works ok with the stock build, however I can't get above edge speeds as the baseband/radio doesn't support the 3G frequencies used in canada. Through searching this forum I found I5800LVIJG8 that is supposed to be for North America. Does this mean that a version of the 5800 existed that supports north american 3G frequencies? If so, are there actual hardware differences? I also read of users having I5800L or I5800D's and using them in Canada. Are these versions with the suffix different hardware versions to support the different 3G frequencies?
Lastly, if I5800LVIJG8 does support 3G, it is a froyo ROM. I have read that there are differences in the baseband files between Froyo and Gingerbread, making them incompatible. Are there other options? Will other gingerbread or ICS based roms such as Cyanogenmod work with a Froyo baseband?
Thanks for your help, it would help me make this otherwise crippled phone useful if I could get 3G on it.

Hello,
Haven't been here for a while and saw the treads saying the G930T is flashable with the unlocked version, so I am excited to do that when I get home. I currently using Cricket, which is a subsidiary of AT&T, so I was thinking of flashing the AT&T bands. Would this cause any problems? I saw others have flashed the T-Mobile with no problems to keep wifi calling, but considering I don't need those, would I even see a performance increase for using the AT&T bands on the G930T? That is the only reason I was considering it.
Lastly, I was on the Sammobile site, but there are two versions of the 930U listed, one as USA and one as USA: T-Mobile (https://www.sammobile.com/firmwares/galaxy-s7/SM-G930U/). Do I need to use one over the other?
Thanks for the help!
