Blackberry Traffic is an application exclusively built for Blackberry OS. This application is among top featured apps for Blackberry Smartphones which, based on the traffic conditions, can tell you your estimated time of arrival (ETA). It also shows alternative routes to save you from the hold ups, toll booths, and help you reach the destination easily. So, you can inform your contacts about your ETA. It also supports turn-by-turn navigation through voice instructions which can be integrated with either Bluetooth Stereo headsets or the inbuilt sound system of your vehicle.
