I have the 4 with AT&T and its 27 months old and is crapping out on me. Best But will actually give me $230 trade in value for the phone. So I can get a FREE 4S, or should I pay the $200 and renew AT&T contract. I guess I need to know or find out of I trade on phone to Best Buy if I can use credit for a 5. I'm thinking I can't do that, but you guys know a lot more than me about this. Thanks...
