This weekend RIM released BlackBerry Desktop Software 184.108.40.206 for PCs in the BlackBerry Beta Zone. The update is just a small version bump from the v220.127.116.11 that was in the Beta Zone before. Just like the previous version this new Beta of Desktop Software has also been leaked and stripped of its keycode requirement thanks to the OSBB team.
You can sign up for the official version in the Beta Zone or pick up the installer and userguide directly from OSBB leaked keycode free version. If you have the bandwidth post up some mirrors in the comments in case it gets yanked down!
