I have a month-old 3g iPad. Was working perfectly for the first 3 weeks. Now in Safari, and some other applications, the screen will start moving around by itself, scrolling up and down, zooming in and out, and even jumping to new pages via hyperlinks even though I am not touching the screen at all. The iPad is not jailbroken. I did a restore as new, which worked for a few days, but now it's happening again. Has anyone else experienced this?
