Research in Motion (RIM) has released a software update for its BlackBerry PlayBook tablet.

Version 2.0.1.358 is available to download and bring a few enhancements to the 7-inch device.  The smartphone and tablet maker launched PlayBook OS 2.0 back in February bringing with it native email, calendar and contact.

RIM hasn't given a very detailed list of the improvements saying that it includes:

•    Browser enhancements to address performance with some websites
•    Improvements to support Android apps
•    Optimizations to Video Chat, PIM [personal information manager] and BlackBerry Bridge applications
•    And much more!

Users should receive a notification about the over-the-air (OTA) upgrade but can also manually check within the settings menu.
