So now I have a huge problem. I bought this iPhone from a person on craigslist saying it was AT&T, and it showed AT&T 13.0 on the carrier but after I restored it, it says its a Sprint iPhone 5. I called sprint and they confirmed it is for their network. I am completely confused right now. I know for a fact Sprint iPhone 5's are not cross network compatible with AT&T so why is this. I'm going to take into apple this week sometime hopefully.
