hi, ive had my phone for nearly a year now with no problems at all (apart from my lock button being broken) BUT today i updated my phone to 6.1.2 (i think) after the update my phone was saying that the sim card was not inside the phone. i tried taking the sim out of phone and putting it back in - no change. i tried turning phone on and off (with assistive touch, since lock button broken) also with no change. after this i restored my phone to see if that would resolve the problem. after the restore i went trough the set up on my phone but now the problem i have is that at the end of the set up my phone will not activate (i have tried connect phone to itunes and wifi connection) i get the message "We're sorry, we are unable to continue with your activation at this time." i can not turn my phone off so i am stuck in the set up. could anyone sugest anything? p.s the phone has not been jail broken and nothing has been tampered with in the phone settings. also use a mac to connect to phone. thanks.
