my charger cord works fine for my Ipod 1. but when i plug my ipod 4 into my computer, it wont read it. It was completely dead, and i just got it from someone on ebay. so idk if there was any internal damage during the mailing process, OR if the guy that i bought it from sold my a bogus ipod that he knew wouldnt charge. either way, the ipod 4 wont charge. i have it plugged in and it shows a battery with a little red bar and a lightning bolt under it. do i need a knew cord for a 4th gen ipod vs a 1st gen? and what do i need to use to clean my port without damaging it further? gah. ive never really knew much about apple products.. needin some help from an apple genius :3 haha edit: like every 5-10 mins it lights up with the apple symbol but then goes back to a black screen afterwards. also before i had plugged it into the computer, i had it plugged into an adapter into the wall and it said "not supported with this accessory"
