This looks like a really nifty application; combine the GPS in your Blackberry with real time traffic information, and some smart thinking, and you get an application that can tell you the best time to leave so you can make your appointment.

• get “when to leave alerts” aware of real-time traffic
• see the optimum (fastest) route avoiding congestion
• confirm on-route you will arrive on-schedule
• store customized locations
• check daily commute for accidents and construction
• all automated on your blackberry® for the most convenient and accurate advanced traveler information solution ever.

The application is still in beta, but you can give them your email address and they’ll invite you as soon as possible.
