I have a 15 GB, 3rd generation iPod that I've had since around July. It's been working great, but for the last few days, all that's been showing on the screen is that black Apple logo. It doesn't respond to any button pushings. I've held down Play, I've held down Play and Menu, but it doesn't respond. I've made sure it's not on Hold (flipped the Hold switch back and forth numerous times); plugged in the wired remote and tried to use that; plugged the iPod directly into my computer; plugged the iPod into my computer through its Dock; plugged the iPod directly into an outlet (using its adapter); plugged it directly into an outlet (using its adapter) through the Dock...but it just keeps showing a somewhat darkened screen with an Apple logo in the middle. Is there anything I can do? Or do I have to send it in to Apple and have it fixed/replaced?
