I have a 4G iPod 20GB and a 1G iPod nano. The 20Gb came with a firewire cable, a usb cable, and a wall charger that works with the firewire cable. Should the firewire cable and charger work with the Nano? It currently doesn't, I am just trying to figure out if it should. If it is not supposed to, i won't worry about it, if it should, then I may have a problem with my nano and need to send it back for repair. The USB cable works fine in the Nano. I was under the impression the dockable iPods were somewhat universal and that what fits and works in one, fits and works in others.
