Okay so I recently lost/got it stolen my iphone 3g. I don't really want to pay $400 for a new so here's what i'm thinking: 1. One of my friends, who has att service, is willing to buy an iphone under their contract so I can get it at a discounted $200 price (they don't have/want an iphone and eligible for upgrade). Will there be any problems with doing this? 2. if there is a problem, maybe i'll pick up a used iphone 2g. If i do get the 2g, will the data plan be $20/month w/ 200 text messages?
