Hey all, I know there have been alot of posts about faulty screens but I haven't been able to find anything that tackles my problem. On the bottom of my iPod touch LCD screen there is a thin gray digital line that won't go away no matter what I do. It appears to break down a little after I use my touch for a while, but then when I turn the ipod off and then back on, the dreadful gray line has somehow restored itself... Does anyone have any suggestions about how to get rid of it? Or do I just need to go exchange for a new one?
