3G continues to freeze iPhone 4S screen. Phone hardly ever used. Purchased at ATT. NOW WHAT?
ATT 3G freezes iPhone 4S touch screen. If 3G is disabled, touch screen works fine. I have reset network, restored iphone with no apps, and it still freezes the touch screen if 3G is enabled. I called ATT tech support, they said my iphone should work with 3G enabled. Yet, it does not. If I enable 3G, ATT connection bar drops to 1 or 2 and screen freezes. I've tried other locations, it still freezes. Any help would be appreciated.
