Although I'm not a big BlackBerry fan, I can't help but think having the Open Source Wordpress for BlackBerry application on the device would be pretty cool. This application for writing, managing, and editing your blog works whether your blog is found at Wordpress.com or self-hosted.
BlackBerry operating system OS requirements are OS 4.2.1 or newer. In other words, Wordpress for BlackBerry should work on any of the newer BlackBerry smartphones including the 8700, Pearl, Curve, Bold, and Storm.
The BlackBerry application is currently in beta.
