i dunno if i should post this under here, but i got a really annoying problem. i got an ipod mini and everyday i let it charge for the whole day. when i want to use it, i can play about one song, then it says low battery on teh damn thing. after charging for more than enough time and the bar actually says that its charged, the ipod says its low on batteries and dies.what the hell is going on? and is there a way to replace the battery inside?
