I currently have an iPhone 4S on AT&T that I got when it was released last year and am still on my 2-year contract until May 08, 2013. My wife is on T-Mobile using an unlocked iPhone 4 and is off contract. The end goal is to have both of us on a shared AT&T plan. Me with the new iPhone 5 and my wife with my current iPhone 4S. I could do the early upgrade, buy the iPhone 5 for myself and eat the $250 fee (total $649.00) and then my wife could get a new iPhone 4S for $99. But that seems ridiculous since we're adding a new subscriber. Is it possible to buy the iPhone 5 for my wife, for $399.00 as a new customer, then once everything is up and running, swap phones with her so she's using my iPhone 4S and I get the iPhone 5? I know the sim cards are different so we can't just swap the sim cards ourselves. But could we maybe go into an AT&T store and have them do the reconfiguring after we do the purchase? Or are they potentially going to be annoying about that? I'm not being mean stealing the iPhone 5 BTW, she just doesn't care. cheers.
