According to the Bluetooth DUN Compatability list (please excuse the formatting - hopefully only a temporary problem) the V3 Razr should support DUN. It sounds like you've done the right things so far: pair the phone and N800, flag the N800 as trusted on the phone then surf the web. I did find bug #1217 which may be the cause of your problem, give it a go and see if it makes any difference. To change details... 1. Go into Control Panel -> Connectivity, press Connections button 2. Select your Bluetooth phone connection then Edit button 3. Next 4. Change username, password and address ("Access point name" in dialog) as per bug #1217 5. Finish Hope it helps. EDIT: I need to learn to type faster...
