I had to return my previous iPod because the unit does not hold it's charge overnight and it also does not stop charging no matter how long it's been on for. Problem fixed and I got a replacement under DOA guidelines. However, it seems to be happening again! It's eight hours since it's been charging on the dock and it's still going. I seriously don't want to go back and wait for almost a week to get another one so I'm desperate to know if anybody else has had this problem or of anyone knows what the remedy is. Thanx for any help.
