I’m writing a non-phone item for O’Reilly’s Digital Media Center related to LEGO Mindstorms NXT and ran into this LEGO provided NXT Mobile Phone Application that lets you control an NXT bot from a Bluetooth phone. It works with a couple of Nokia, Sony-Ericsson, and BenQ-Siemens phones. No Window Mobile support. However, you can find an unofficial Microsoft developed Window Mobile project for LEGO Mindstorms NXT called WiMo the Windows Mobile Robot.
