I have an iPhone 4S and would like to switch its carrier.
Hey! My friend is in a really bad place right now, and they need a working cell phone. Their phone is an older Samsung cell, and the 9 key has become irreparably sticky, rendering the phone unusable since it auto-speed-dials me when they turn the phone on. That's beside the point, though. I have an iPhone 4S that I'm not using that I'd like to give to them to use, that's currently updated to iOS7 and has not been jailbroken. My carrier is Verizon, and theirs is AT&T. Is it possible to switch my iPhone 4S to AT&T for them to use?
