Freeze during call on every VoIP app on 3G Data...
When I call over 3g Data with my iPhone, VoIP apps freeze... I can still talk, but when the call ends, I can't click on anything, every thing is frozen, I can't click end, home button nor power button...After the freeze, my phone restarts itself and everything is back to normal. Also, the app hangs during a call and the phone restarts on it's own... it's really annoying...Does anyone have this problem?
