I have a new 5th gen Nano. My stereo/portable/alarm clock all use a firewire dock, so that sucks, I cannot charge my new Nano. I heard there will be/is an adaptor for inserting into docks. I cannot find them anywhere. I have found a long cable that converts the old firewire charge to USB charge, but is there a more elegant solution? Perhaps one that fits a typical dock to a stereo?
