Yeah. I'm thinking about the back up, too. You keep the back up, don't you? If you don't, you will be in big trouble. AT&T mail you the phone first, but they charge you in the bill like you buy a new phone. When you have send your phone back, they put the credit in the bill balance. If you debrand it, I don't think they would accept it, and you won't have the money back from them.
