RIM (Research In Motion) has started rolling out a new software update for its first ever tablet the Playbook. The new software update brings some performance enhancements and stability improvements.

The update also includes an updated Facebook book application, optimized for the Playbook. With this update, Playbook users can also charge the tablet whilst it’s fully powered off. The tablet will also display an error if an incompatible charger is used to charge it.

RIM has also added a small but handy power menu, when a user taps on the battery icon. The power menu provides users with options to shut down, restart or put the Playbook on Standby mode, along with a brightness slider.

The update also brings in-app payments support to all Playbook compatible apps. RIM has also updated the developer tools with support for in-app payments.

Aside from the changes stated above, the video call quality has also been tweaked, with support for TURN (Traversal Using Relay NAT).   Some additional language support for the tablet has also been included.

Sadly, this update does bring the much awaited Mail app to the Playbook. Until the next update arrives, Playbook users still need to use their BlackBerry handset to sync mails between these RIM devices.
