Nick let me know that Hotels.com has a pretty good mobile site that I had not mentioned before. It lets you search for hotels by city, state, location, and name and view your reservations.
Pretty cool if I may say so myself. Definitely worth a bookmark for the regular traveler. It just seems to have a weird zoom issue on the Bolds browser where you need to zoom in every page.
Check it out by heading to www.hotels.com from your BlackBerry browser
