MobileJustice is a freeware anti theft application for Windows Mobile 5.0 based devices that allows you to monitor and search your mobile phone via GPS coordinates.

The application consists of four modules:

1. SimMon (sim card monitor, started at windows startup)
2. RemoteMonitor(parses incoming SMS messages and sending replies)
3. GpsReport (get GPS position and send it to phones listed in command line)
4. MJConfig (configuration utility)

Once you’ve installed the CAB file, you need run SimMon and select “Enable” checkbox against Enable/Disable SimMonitor option. Then you will need to add all the phone numbers that will be used on the mobile phone. In the Report To list, you can define all phone numbers where an SMS warning will be sent in case a SIM card change is detected.

Similiarly, you will need to configure the other modules the documentation for which can be found here

Once everything is configured successfully, the application will run in the background. In case, your mobile is stolen or lost, you can send an SMS to the mobile device and you will get a reply with the GPS coordinates where your device is located.
