Can I unlock my AT&T iPhone 4s to work with Sprint?
Okay, so I bought an iphone 4s with AT&T in February. My mom is thinking about cancelling the plans and paying the fee.So, is it possible that I can ask AT&T to unlock my phone so I can use it on Sprint? By the way it is a world phone so it has GSM/CDMA so yeah it does work. It's running iOS 5.1.1
