Ive had my Ipod for under 5 months and it was working just fine, now one side of my headphones doesn't play (the right). Ive changed my headphones about 4 times now, hoping that it was just my headphones, but its the actual Ipod. (I've tried the headphones on other items and they all worked fine.) I sent it in to get fixed, since its still under the warrenty.. but they sent it back to me saying there was nothing wrong with it, even though.. its still not playing on the one side. What can i do to fix this problem? It drives me nuts not being able to hear my music properly.
