I recently upgraded my iPhone 4 from 4.1 to 4.3.3 through redsn0w 0.9.6rc16. After I installed all of my old packages from cydia, it intermittently stops responding when I receive a call or text. The lock button and the volume buttons will function fine, the lock button blacking out the screen and the volume buttons silencing the phone but the touchscreen is unresponsive and I end up having to press the lock button twice to be able to slide to unlock the phone. This isn't a big deal when receiving a text but I essentially have to ignore the call and call the person back when it comes to voice. Is anyone experiencing similar issues?
