Running 4.3.1 jailbroken yesterday...when I flip my silencer switch to silent it'suppose to vibrate but now it's not vibrating. When I flip the switch back to on, it also vibrates when it did not before. I can't figure out where in the customize settings for the different switches/buttons I need to go to turn something off, it's really driving me crazy as I need the physical feedback from feeling the vibrate.
