Tracker is a GPS tracking tool for Windows Mobile.

Tracker writes a track log to your My Documents folder while it's running. When you exit Tracker it will generate a Google Earth KML file and some statistics (distance, time taken, total elevation gain and average speed). Both the track log and KML file are saved with the current date in the file name. Tracker will prevent your device from powering off while it's running, so you can just kick if off and then lock your phone while it's running.
