I've developed several strange issues on my 3GS that I've never seen before and was wondering if anyone might know what's causing them: 1) My wallpaper disappears and the statusbar on the homescreen becomes stuck in a horizontal position. 2) The lock screen becomes distorted; it appears to be horizontal and wider than the screen, with the home screen showing above and below the lock screen. The "Slide to unlock..." slider becomes wider than the screen, making it impossible to unlock the phone. 3) The Voice Control screen appears zoomed. If anyone has any ideas what could be causing this, I would much appreciate some advice.
