I restaure my iphone 3 and now when I try to ativate it the i tunes don´t recognize the SIM inside the phone. Someone have any idea about this problem?
Sounds like the iPhone had previously been hacked/modified/jailbroken
and the restore has relocked it to the original carrier.
What does it say when you look at Settings=>General=>Carrier?
Does the app Cydia appear on your iPhone?
