We mentioned TripIt over a year ago as a competitor to WorldMate Live for importing and managing your itinerary on your BlackBerry. They currently only have a mobile website which is decent but they just announced that they are beta testing a full BlackBerry application. They are also looking for beta testers if you are interested.
The interesting part is that TripIt plans on remaining free so that is one less worry. I am not sure how they will be making their money but I am guessing up-selling will be involved.
Let us know if you get into the beta testing group!
