RIM has just released BlackBerry Traffic v3.0 into the Beta Zone, and boy, it’s a great update. This new beta version of BlackBerry Traffic brings what may be one of the most requested features, turn-by-turn voice navigation, to this popular BlackBerry app. In addition to the turn-by-turn navigation, BlackBerry Traffic brings you real-time traffic information, road construction, and road closure alerts. You can also plan your route and get an estimated arrival time based on the road conditions of your route. BlackBerry Traffic is free to all users and available for download in the BlackBerry Beta Zone.
