I have an AT&T iPhone 4 that my friend gave me once her contract was up. She contacted AT&T for them to unlock it which they did. However, when I try to activate it now, I get the message "We're sorry, we are unable to continue with your activation at this time. Please try again later, or contact customer care."
I do not have an AT&T SIM for the phone, nor do I have easy access to one (I'm currently in Cambodia). Can I activate the phone without an AT&T SIM? It seems like I should be able to since AT&T claims to have already unlocked it.
Any suggestions would be appreciated.
Did you restore the phone in iTunes, which is needed to complete the unlock process (or did your friend do it)?
