I requested an unlock from AT&T about a week ago and got an email back saying the request has been approved and to plug in my phone and do a restore. I did that but I didn't see the expected "Congratulations your phone has been unlocked at the end", it just came up in iTunes asking if I want to restore as a new phone or from a previous backup.
Any way to check if it worked? I don't have an T-Mobile nano SIM to test it.
