withen the past 2 months my iPhone will randomly not "slide to answer" when i get a call. its as if the phone does not respond at all. the ohone will ring and display the caller info but the touchscreen does not work, neither to the volume button, home, or sleep button. it is jailbroken 1.1.4 no other problems to speak of. after the call is missed i have to reboot the phone to get it to work(sleep+home). anyone know whats going on?
