Bought my touch from SAMs over the summer last year. It stopped working so I was able to get a replacement for the 2G. I currently have the touch rebel case on there. If I were to take the case of and use the ipod, the back will get scratched right? If so, would SAMs still accept the touch if something were to go wrong? I have a 5 yr warranty on this product... I just don't want them to say "your back is scratched so this voids the warranty." Any ideas?
