With RIM having now release the BlackBerry PlayBook Native SDK version 2.0 and updating the BlackBerry PlayBook simulator, it only seems fitting that they would also go ahead and update the developer build of the BlackBerry PlayBook OS 2.0 as well and they've done just that. If you've signed up for the Native SDK 2.0 download you can now also punch in your PlayBook PIN and download the new PlayBook OS v2.0.0.4869.

Keep in mind, this is a developer build and not for the general public -- things are broken and there is dragons ahead. No telling what, exactly as of yet but if you download it be sure to let everyone else know what you spot -- right now, we can say you'll get a look at the new LED notification system.
