is this with every new ipod now? i have the black bose sounddock. not the new sounddocks mine is when they first started making the black colored ones. My 2 yr old 160gb classic charges on their, but the nano 5g says not supported for charging. it plays it fine and the remote works, but it won't charge. is this with all the new ipods? even the new classics and how long has it been going on.
