My iPod has an issue with the screen. Say for instance I'm on a picture that is completely black. At maximum brightness, when I tilt the iPod, I see A BUNCH of white spots and dark spots. I also see what appears to be some thick lines of light on all 4 sides. Is apple going to replace my iPod because of this? It really is annoying when scrolling through pictures, you can tell what is distorted when sliding a picture. Also, this will be my 4th replacement iPod. 1st one had a huge light leak, 2nd one had dead pixels, and the 3rd one had a messed up speaker.
