RIM is pushing out a new OS 2.0 developer beta for the BlackBerry PlayBook. OS 18.104.22.16849 is now officially available for those running OS 2.0. The update is said to bring support for new languages, BlackBerry Bridge updates, and multimedia enhancements. It is likely RIM worked on patching security holes the DingleBerry exploit took advantage of. If you find anything else, do let us know.
