has anyone had their 3rd gen iPod replaced recently due to the battery issue? I am starting to notice that my ipod won't even get me through a week's worth of work travel before needing to be charged. I would say that I use it about an hour or less each day. I am going to "test" it as the recommend to see if the battery has seriously declined. If so, do you just take it in to the store for this? Any help = appreciated.
