How can I tell if my iPhone is unlocked?
I had an old iPhone 5 for which I submitted request to AT&T to unlock the phone. I received instructions from AT&T to connect to iTunes with cable, backup my iPhone, and then Restore again. The instructions said that once I complete backup-restore activity my iPhone would be unlocked. I received an error during the Restore step (backup device uncompatible..). My question is how can I tell if my iPhone is unlocked or not? Thanks in advance for your help.
iPhone 5, iOS 8.1.2
