Probably been discussed before, but I couldn't find anything when searching. A mate has a new PB and an Airport Extreme Base Station. He has Broadband via a USB ADSL modem, which is currently connected to a PC. Is the USB port on the base station usable with this modem? I thought not, but can't see any other way for him to get the internet onto his PB without buying a new modem with an ethernet port. Any suggestions that may help?
