My good pal, Matt Miller, The Moble Gadgeteer blogger over a ZDNet, gives a good demo and detailed instructions on how to tether the Nokia N95's integrated GPS and modem with the Nokia N800 Internet Tablet, all via Bluetooth. Basically, you need Symarctic ExtGPS app installed on the N95 which will allow other devices (mac, pc, linux included) to use its GPS, a data plan to have the N95 connect to the internet, and Maemo Mapper. What is interesting is that both the GPS and modem are working together via one (or maybe two) Bluetooth connection(s) to the N800. Thanks Matt! Read Matt's full writeup.
