I've been contemplating getting a new iPod Nano, but I recently got my old 5th gen out and remembered how much I love it. It's pretty beat up, but it is still my favorite iPod Nano design. The only thing is, the battery's been dead so long so much that it's shot. It will only hold a charge for a few hours. Will Apple still replace these batteries? Is there any place I can go to get a new one installed? Thanks!
