iPod wont Charge once in a while
then recently it would not charge even after it was connected to the power adaptor for over 12 hours.
i reconnected it then and it charged okay.
then 2 nights ago it would not charge for a second time, this time after tweeking with the cable for a bit it finally charged.
i wanted to see if it was a recurring problem so i tried charging it again, it started out with half power and 4 hours later, still there.
has anyone else experienced this? can/should i get an exchange?
