It's a quad band gsm phone so if you buy an import it will work fine on either at&t or t-mobile. You just won't get the high speed data connection. You can still make calls, sms, mms, and get data at the slower edge speeds. I may consider this if the price comes down because I never intended to buy it as my primary phone; I would use it as a secondary internet tablet/MID and I can always pair it with my 3G phone.
