Mologogo is a free GPS friend-tracking service that works on Nextel phones with Java and GPS. Over at the MAKE: Blog, Phil Torronne took Mologogo for a walk. It’s a really cool use of the Google Maps API. This one lets two (or more) people you use GPS enabled phone to show on a map where they are in relationship to each other.

Cool little friend finder application there. But now they just need to make a GPS enabled Motorola RAZR so I can use it.
