One of my favorite applications, Trapster for Blackberry, was updated to version 4.0. For those who don't know, Trapster is a traffic application that uses your GPS to let you know about upcoming speed traps. There are over 7 million Trapster users that update when they spot police waiting to catch you speeding. The application was recently updated to include things like school zones, children playing and roadkill. Also included in this update is improved performance. I've used Trapster for a long time and 4.0 seems to be the best version yet. Make sure to download the application and drop us a comment in the forums to let us know what you use Trapster for.
