Hello,
my iPhone 3G started showing a white screen with black stripes both horizontal and vertical, that comes and go randomly without my being able to detect a cause. The only thing that allows it to get back to normal is to PRESS the up-right corner of the iphone real hard. Since it doesn't involve any other malfunction than the screen (when it comes, I can still hear the sounds of a youtube video, the ipod or a call), I figured it must be a screen problem. THE REAL problem is that I had the screen changed at an Apple Store, it worked right for like 10 days and then it all came back again. Don't know what to do...
