I purchased an iPod Nano this evening for which the headphone doesn't seem to work. Aaarg...and I will need to mail it off to get a replacement or return. Has anyone had this problem and been able to fix it? I can't find anything on the internet about it, so am assuming that I just got a bad one - but you never know. I got it so I don't have to use my rather more expensive phone at the gym to listen to music....
