WapReview

BlackBerryForums is one of the most popular of the dedicated BlackBerry user forums as well as one of the few with a mobile formatted edition (wap.blackberryforums.com).   With over a million posts and 200,000+ registered users, the five year old site is a incredible resource for users of the popular email oriented smartphone.

BlackBerryForums Mobile uses the popular WiForums add-on, which works with a variety of popular PHP based forum software including vBulletin which is what BlackBerryForums uses.  The version of WiForums used is quite slick.  There's a a fully functional search to quickly find what you are looking for among those million posts. WiForums is highly configurable, using the "My Prefs" option on the home screen you can turn images in posts on and off (beware that images are not re-sized), set the number of posts and threads per page and the number of search results returned.

Registration is not required to browse the mobile edition of BlackBerryForums but only registed users can post, update their preferences and download files hosted on the site. You can register right on the mobile site, which I recommend as the registration form on BlackBerryReview's full  site has one of the most hellish CAPTCAs I've ever used.
