RIM has announced the availability of BlackBerry OS 2.0 for its PlayBook tablet, Mashable reports.

The new version of the OS brings social integration with services such as Facebook and Twitter, speedier operation with the help of real-time multitasking and several new productivity tools including Documents To Go, which lets you view and edit Microsoft Word, Excel and PowerPoint files.

BlackBerry OS 2.0 for PlayBook also packs native calendar, contacts and messages apps – something the initial version sorely lacked.

BlackBerry Bridge is another new feature that lets the user seamlessly switch between screens of BlackBerry smartphone and the PlayBook. It also allows using the smartphone as a keyboard and mouse for the tablet.

BlackBerry PlayBook users can get the new OS by checking for updates in “Settings.”
