BlackBerry Tracker is a free web based GPS location and tracking client for Blackberry mobile devices that can function as an anti-theft application too. After you sign up for a new account and activate it, you need to install the Java based client on the smartphone. Then you can launch the program from the home screen and login using your credentials, letting the software run in the background.

Here are the main features of Blackberry Tracker:

Live Tracking: This feature allows you to track your Blackberry on the web. Once the Blackberry Tracker application is running on the device, GPS coordinates are sent to a specified server at an interval specified by you (for eg. 30 seconds, 60 seconds, etc,.).

Tracking History: The program accumulates a history of your GPS data online. You can see the path of your phone between any two dates by selecting Tracking History.

Track Friends: You can also track/get tracked by your friends and family by asking them to sign up for an account. After they have signed up, all they need to do is search for you under Find User and then select Track this user’s location. After they have permission from you, they can go under Track Friends on the home page to begin finding your location!.

GeoFence: Now you can be notified whenever your device enters or leaves a GeoFence. A GeoFence is an imaginary circular fence around a specific point. When you create your GeoFence you specify a center location, click on a point away from that point, and your fence is automatically created
