I have a 1st generation iPhone that was unlocked and jailbroken with ZiPhone. One day I was typing a text message/using internet (can't recall specifically) and a bunch of random keys popped up (as they do when you type) even though I had not pressed anything, and since then a portion of the screen no longer works. This portion is (in the context of text messaging), the top row of the keyboard, and the area where you have the actual message (hence I cannot press 'send'). I repeatedly tried the reset technique involving holding the home button and power button, but had no results. Recently I have reset the home screen and now have a "how to rearrange home screen icons" thing in the middle of my screen whenever I turn the phone on, and I cannot press "ok" due to the problems in the screen. Any idea what the problem may be, or what I can do about it? Thanks!!!!
