I really wish I could, i had tmobile for 2-3 years before i moved to nebraska... However they dont have service here, let alone even coverage (a friend was in town recently with Tmobile and couldnt get a signal at all).
On the bright side, i went to the ATT store (a few miles away) got a 8gb iphone and have it activated and working ALREADY. 36 dollar activation fee was it.
