N97 mini
Modes: GSM 850 / 900 / 1800 / 1900
WCDMA 850 / 1900 / 2100
versions for some regions have WCDMA 900 instead of WCDMA 850
AT&T mostly uses EDGE (GSM) in the 850 band and UMTS (WCDMA) in the 1900 band.
It does say the bands vary by the region the phone is from though. As long as you've got 850 and 1900 support for both gsm and wcdma you're compatable with every network configuation at&t has set up.
T-mobile uses an unusual band for their 3G called the aws (1700) band. It's not listed as one of the supported WCDMA bands on the phone.

T-mobile's GSM is 1900 so you're just fine for 2G but that would be it.
It's interesting that this came up i'm actually writing an article for phonecan.com on this very topic right now.
Tried the Torch from ATT and the screen blacked out the fourth day I had it! So back to Nokia I go but we know that ATT does not have mid to high end Nokias. I will check out the article too! When will it be finished? What is the name of the article on the site?
The working title is "device unlocking - demystified" we'll see if i think of anything more creative before i submit it.
I have a real nice table i made up that shows the bands different companies use around the world. Nice resource for "band matching" which you need to do sometimes.
You are right, nothin but nokia flips these days. If you buy no contract unlocked phones you have some options though. Just match the bands, for AT&T you want GSM 850 and WCDMA 1900. For T-mobile you want GSM 1900 and WCDMA 1700

I don't know a whole lot about the phone. If you don't mind buying a no contract unsubsidized phone- and it sounds like you did before you have more options than what your carrier sells.
There's a lot of these phones out there, on other sites as well, amazon sells them too. You can triple your selection, maybe more. There is a niche market of customers out there that want postpaid service but won't enter into a contract under any circumstances. Also people who want their device to be unlocked at purchase and not have to deal with their carriers device unlocking policies.
It's amazing what you can find. AT&T hasn't c...
