Hi all please suggest when the software of iphone is updated does it needs to be reactivated through AT&T or not. Also, when the software is restored then does it needs to be activated through At&t.
Thanksfor reply. But i have a turbo sim installed and using in singapore. Will the iphone be able to activate after restoring.Yes it does but it does it right in iTunes and takes less than 10 seconds to complete the activation.
