I would love to change over to T-mobile for the contract free phones and international data... 2 things are keeping me from switching: 1. Coverage in my city (Memphis/Germantown) is not great with T-Mobile and 2. Since almost everyone I talk to is on ATT, I can pay for the lowest minutes plan since talking to them doesn't cost me anything. Right now, with discount, I pay $68 a month for unlimited data (grandfathered) and 450 min a month (rollover bank has over 2,000 minutes) for my iphone. It's going to be tough to get away from that...
