I have an iPhone 3GS with 3.1.2 jailbroken and with an odd problem. Whenever I plug the device into the wall, all touch recognition hell breaks loose. A simple tap on the screen results and random actions all over the screen. For example, if I tap on the Mail icon, the screen would jitter and then SBSettings would slide down, even though Mail and SBSettings are no where near each other on the screen. And the strangest thing is, it only happens when it's plugged into a wall. When I charge it with my computer, it runs fine. I have two cords and five wall chargers, yet the phone never wants to cooperate when in the wall. Any suggestions? Thanks ahead of time.
