I have the iGo Think Outside Ultra-Slim Bluetooth Keyboard. I Have used it with my PPC6700 but there were drivers for Windows Mobile. I have it paired with my n800 but that is as far as I got. I am a Linux noobie. I looked on the mobilityelectronics driver webpage for "Nokia other" but nothing shows. There does not seem to be a hardware keyboard selection for a BT KB pre-installed on the n800
