My brother's moving home and bringing his unlocked iPhone 3G from Australia to the US. ATT said he needs to sign a 2 yr agreement, which doesn't make sense for him b/c he should just buy a new one for the subsidized rate if he does that. So he's on T-Mobile, but doesn't have data except through wifi. What do people do in this situation? Would jailbreaking it give him better options to use data? Note: I searched the forums and couldn't find my exact answer. People's questions were about visiting the US, not moving here permanently, and buying a sim card from Walmart won't help here. Thanks for the help!!!
