Hi All, I have been getting this problem for a while now and it is very irritating! Sometimes during a call I get cut off from the caller, I don't get a lost connection tone or anything there is just silence. Then when I press the end call button the iphone says ending call and stays like that. If I press the home key I am taken to the home screen with the a message at the top of the screen as if the call is still in progress when I press the lock button it locks the phone and has the call as still in progress at the top of the screen, When I unlock it it takes me back into the call as if it is still on going!!!!! The only way to end the call is to reboot the phone. I have tried formatting the phone and changing the carrier settings with no joy. Is anyone else getting this issue! HELP Cheers, Austin.
