GeoLocME provides free online tracking of your RIM BlackBerry Smartphone! GeoLocME installs on your OS 4.2 or later Blackberry device (8100, 8300, 8700, 8800, 9000, and others) and runs in the background sending your location to the GeoLocME member portal every 60 minutes (default). Registered users can log in and view their location, the location of other users, and control preferences such as nickname and if their location is shared with others.

Install via BlackBerry Desktop Manager (.zip download) or Over The Air (OTA) - OTA install available at www.geolocme.com/app/
