I've read a lot of things about people trying to enable an aws band on the ATT one to get better T-Mobile data speeds. Or converting the phone completley to a T-Mobile edition.
Since I know enabling the aws band is not possible as of now, I just wanted to get a discussion going for people who are using an unlocked One with the T-Mobile network in refarmed areas.
What radios are y'all using to get the best 1900 data speeds?
Since the aws band is not available, does it really help to flash a T-Mobile radio?
And when you flash a ROM do you select T-Mobile in the device selection in aroma?

Trying to figure this out, Is the hardware basically the same. I read alot about UMTS and WCDMA, I am familiar with GSM vs CDMA, but I am not sure if this could work or not.
Basically I am wondering if a Google G1 on AT&T can run at 3G speeds. No need to tell you all the phone specs, I am sure your all aware.
AT&T
GSM 850/900/1800/1900MHz, UMTS 850/1900/2100MHz
TMOBILE
GSM 850/900/1800/1900MHz, HSPDA/WCDMA:1700/2100 MHz
Anyways from my HTC phones with AT&T I usually use 1900&2100 MHz
Is it possible to get this thing running on AT&T 2100, I figure if I was always roaming it would have to barrow some part of the TMO network, or does roaming only default to GSM 2G.
Another thing I think of is maybe updating my simcard with cingular so I can get a bigger network list or am I just dreaming about the whole Idea. It really seems like a software problem. Does that radio chip really make that much of a difference.
Again, is this not just a radio-build/sim config???
Thanks for any input....

It is not possible because the G1's HARDWARE does not support AT&T 3G. Only T-Mobile.
Im pretty sure you could use the rodgers g1 though for 3g on att
Yes the Rogers G1 has the same frequency as AT&T
Hi everyone i tried searching but didn't come up with anything. I'm considering purchasing an unlocked nexus one on amazon and I'm not sure if its a tmobile or att version I have tmobile as my provider if i were to get an att version would i still get 3g access? I know if it was the opposite i there would be no access for 3g on att.
Thanks
I believe t-mobile's 3g is 2100mhz, which means the atnt one should work on the network.
I'd get a second opinion though, I'm more knowledgeable on Australian networks than US ones.
Ok thank you for the input, if anyone could confirm this that would b great.
The devices are completely independent of one another in regards to 3G. Cross network compatability only extends to Edge services.
Someone jump in and correct me if I am wrong, but I believe that T-Mobile 3G requires both the 1900 and 2100 frequencies to work (up & down link).
Rod3 is correct the at&t version will not work on t-mo and the t-mo version will not work on at&t, in respect to the 3G that is you will still get edge either way.
Although as far as the both 1900MHz and 2100MHz I'm not sure about that but it's possible, anyone care to add some info.
EDIT: Just Googled it and it's 1900MHz for 2G and 1700MHz/2100MHz for 3G encase anyone is interested.
Dude, thanks for the correction. I knew there were 2 frequencies for 3G and I just picked one off the top of my head. Now that I think about it, yeah 850 and 1900 were for 2G.
I know this has been talked about in a lot of threads but for some reason I can't wrap my head around it. Let me write down what I understand to be the compatibility and what is not, then please correct me where/if I'm wrong.
T-mo uses the 1700MHz and 2100MHz in conjunction (1700 to send data, 2100 to receive) for their 3G/4G network and plan on the same for their 4G LTE networks.
They are refarming their 1900MHz (currently 2G) to support 3G/4G, but not 4G LTE. The refarmed map is very limited. http://www.airportal.de/
Given the above, the One Dev Edition will be able to get 4G, if in a refarmed area, but once you travel outside you're down to Edge or 2g. Dev Edition will also not be able to get 4G LTE, as that will use the 1700/2100 combo.
I may be saying the same thing you are and if so I apologize.
I believe (and will stand corrected if I am wrong) that currently TMO is using 1700/2100 for their HSPA (3G/4G) network and are in the process of migrating HSPA to 1900.
The One will not operate HSPA on the 1700/2100 system but will work fine on 1900 system so in areas where they've converted to 1900 you'll get 3G/4G otherwise you'll be stuck on 2G (assuming that LTE is not available, which it most likely wouldn't as TMO needs the 1700/2100 for LTE.
The One will operate on LTE in 1700/2100 which is what TMO is intending to do with that system.
I hope that helps.

I'm considering whether to buy an T-Mobile version and unlock it or a "Officially Unlocked" version on HTC's official website. I have found two differences so far.
(1) The first is that T-Mobile version seems to support more 3G networks while Unlocked supports more 4G networks.
Here is something from HTC official website.
Unlocked version
HSPA/WCDMA: 850/1900/2100 MHz
4G LTE: 700/850/AWS/1900 MHz (US)
T-Mobile version
3G - UMTS/ HSPA: 850/ AWS/1900/2100 MHz with HSDPA up to 42 Mbps
4G - LTE: 700 MHz and AWS band
AT&T version
3G - UMTS/ HSPA: 850/1900/2100 MHz with HSDPA up to 21 Mbps
4G - LTE: 700 MHz and AWS band
So does it mean that both Unlocked and TM versions can completely support AT&T network, TM version can completely support TM network (of course), and Unlocked version partly supports TM network (no 3G AWS support). Am I right?
(2) The second is about S-OFF. Neither Revolutionary nor Moonshine mentions the Unlocked version, but they both support TM version.
PS: Can I use more frequency bands by flashing something into an S-OFF HTC One?
If you're going to use it on T-Mobile, why not just buy the T-Mobile version? The unlocked version doesn't have support for AWS bands.

I'm not quite sure which operator will I use.
if your in the USA the tmobile version will probably serve you the best since it can pick up pretty much every companies 3g and 4g signal without problems. tmobile or ATT.
there is currently no way to flash a radio to support other bands not sure if this is even possible currently

I am on a TMobile branded phone, which I unlocked to use with my AT&T account, on which I previously had an iPhone 4S. I've been having some issues getting on LTE so far. I did talk to AT&T several times to make sure that the One was provisioned on my account, and the account was changed to a "4G LTE" data account. I've driven all over the downtown Los Angeles area (downtown, Chinatown, Dodger Stadium, Commerce, and Hollywood) and have yet to see LTE when I'm on AT&T. I get it fine on Tmobile (I picked up a pre-paid Tmob SIM.) I've tried several different APNs (wap.cingular, phone, and pta (which doesn't even connect)). As of right now, I'm a bit stumped as to where the issue might be (it presents itself in Sense, Android Revolution, and Google Edition ROMs). I may just buy an HTC One from AT&T and will put my SIM card in it to see if I get LTE on there, and then return it.
My belief, and what just about everyone has said, is that the TMob phone should be able to get on AT&T's LTE. For whatever reason, and I can't quite lay blame anywhere yet (I'm new to Android, so it could very well be I'm not getting something), it's not working.
So after the denim update, AWS (aka 1700/2100 or LTE Band 4) support for the icon(929) became available, and because of this I purchased the Icon and I love it. However I live in Canada and have a month to month plan with Mobilicity. I guess I didn't do my research well enough (I'd like to think the internet was a bit misleading but....i guess its matter of perspective). Mobilicity solely rely on the AWS band frequency. They don't offer LTE but instead use HSPA . I knew that already but I figured that since AWS was supported I could receive HSPA signal over the 4G radio but nope I was wrong.
So I guess there are enough distinct differences between HSPA on AWS and LTE on AWS enough for them to be not cross compatible? Is this a hardware "issue" or a firmware/software one that I could do something about? Is it possible to enable 2G/3G/HSPA over the 4G radio? Or maybe I can get it to work by setting the APN correctly? I looked at some phones specs over on GSMArena which do offer HSPA + LTE support over AWS, I really want to say that it seems unlikely that 2 or more pieces of hardware are required to offer 2 services on what is essentially the same frequency.
