I'm still continuing with the development of a SOE for our corporate Blackberries. Next up, the Facebook application. Sure, I know it's not necessarily "corporate" but I'd rather that IT does a standard install than the users try to do it themselves. Open your blackberry web browser up to http://www.blackberry.com/facebook Choose Download this program . Scroll through the massive legal disclaimer and choose I Accept then click Next. Choose Download and wait for the Bar Graph. You'll be dropped back in your web browser but should find the icon in the downloads folder.
