Alright guys so I have a friend who is looking into getting an iphone. He just cancelled his at&t service that he had because he wasn't happy with the phone. He is looking into getting the iphone and was wondering which one was better for t-mobile. Does t-mobile have 3g service? Also which data plan have you guys found to be the best for the iphone with t-mobile? does the sidekick data plan work for it? I ask because I have a friend who has the sidekick plan and he only spends like $35 a month. The reason that he wants t-mobile is that it seems to be cheaper than the at&t iphone plan. Thanks for your help and any input on this
