I think I need to purchase a charger for my new iPod Touch (2nd Gen). I have an old firewire charger that doesn't seem to work. The plug fits, but I get a message that the device is not supported. I understand that Apple changed the charging abilities to only handle USB. Seems pretty ridiculous to me. Anyways, my wife has a 3rd generation nano that I would like to be able to charge with the same charger. What would the best charger be to purchase? Anyone using the Apple USB Power adapter? Thanks.
