Looks like RIM has hit us with a surprise update for the BlackBerry PlayBook. The new update is v184.108.40.2068 and it looks to be about 79mb is size. No changelog, but I assume that this update will be performance enhancements and bug fixes. Be sure to let us know of anything else you may notice. Happy updating!
Note: To update your PlayBook. Go to, Options... Software Updates... and select Check Updates. Once prompted to update, select Update. A good tip is to leave your device plugged into a power source.
