A friend was having trouble with his iPhone so I told him I'd take a look. The screen looks reddish, almost sepia, and it's filled with scanlines. When I switch pages the icons get distorted as they move. Also, when looking at menus or apps that have straight lines drawn, such as the contact book, the lines seem to sttuter. It definitely is a hardware problem since it looks like this even during startup, and I also took a snapshot and used my computer to view it and it was just fine. Somebody advised him to reinstall the firmware, I honestly think it won't work. What's should I do? Call apple? Change the screen myself? Thanks.
