Hello all, FaceTime on my iPhone 4 is not activating at all. It keeps saying "Waiting for activation." I tried all of the fixes that have been suggested: hard reset, power cycle, iOS restore, removing and reinserting the SIM card, replacing the SIM card, replacing the iPhone itself.... My iPhone is not jailbroken. It has iOS 4.3. I bought it with iOS 4.2.1. FaceTime was not working with the previous OS. I am located in Japan so the carrier is SoftBank. I have talked with SoftBank and Apple people in my area. But no solution. Could anyone help me???
