AT&T has approved my unlock request, and tells me I have to restore my phone to unlock it. It references an page at Apple's site that says all I have to do is stick in a new SIM card. It only calls for restoring the phone if you want to use the same SIM. I don't want to go to IOS8 just yet, so restoring is not an option for me. What's the truth? Do I have to restore the phone to unlock it?
