Trapster is a very smart choice for all of you that own a mobile phone with integrated GPS system. Once you have installed the Trapster application (free), your phone will automatically alert you when you come close to law enforcement device such as speed trap, red light camera and other goodies. Their database still need refinement so in case you still get pulled over, you can still help...others by adding your location quickly with their mobile widget. Finally you can put this GPS phone to some use !
