TripIt has announced a free BlackBerry app allowing you to access your TripIt itineraries right from your device, with or without data service. The free app includes calendar integration, flight status, hotel & restaurant info and more. To use the app you'll need to register for a TripIt account, and you can then send your itineraries to TripIt where they'll be entered into your "master travel itinerary" so you can monitor your flights and hotel information. From the TripIt application, you can pull up maps and directions, quickly call hotels and airlines and view all of your travel details. To receive flight alerts and other "perks", you'll have to kick in $69/year for TripIt Pro, but you can test it out free for 30 days.
