The other day I was using my iPhone 5 (4G LTE) and then it wouldn't charge anymore, so I switched back to my old iPhone 3 (3G). Now, I got my iPhone 5 to finally turn on and charge again and now I can't switch back to it. I call *611 and it doesn't help me any. All it tells me to do is put the SIM card in my phone and to turn it back on and it should work, but iPhone's don't have that. I just want to switch back to my iPhone 5. Anyone know how to switch back?
