I recently bought a 3G 15 gb iPod from a friend in perfect working condition. when i took it home and connected it to my computer, iTunes told my to either restore or update. i clicked update and it did its thing and then it said to disconnect the iPod. now every time i do connect it to the computer, it tells me that it doesn't recognize the driver. i then went out and bought the wall adapter for the iPod. tested the charger on a friends iPod Nano, and it was charging... so i plugged the 3G 15 gb iPod into it and now all i get is a screen on the iPod telling me to connect it to something... if the computer wont recognize it, and the wall adapter won't charge it... WHAT DO I DO???
