Had jailbroken iphone4 ios 5.0.1. When i made a call, i got no ringing tone and when i pushed end, it just says call ending without refreshing back to the keypad. So i stiched 5.0.1 with ifaith 1.4 and Setup as a new phone & rejailbroke and it's happening again... Anyone had this before? Does this need to be restored to 5.1 and returned to apple?
