i just bought a brand new 4G ipod and it worked great the first couple of weeks.

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?
