If you upgraded to the leaked OS 22.214.171.1248 for the BlackBerry Bold 9700 you probably noticed it includes a newer version of the Facebook for BlackBerry app. The updated Facebook app, version 126.96.36.199, has been extracted and leaked for everyone to download. Keep in mind that this version of the app was extracted from a Bold 9700 OS so it might not work on all devices. You can download the leak from here thanks to MyBBOTA.

DISCLAIMER: Install at your own risk. This is Leaked/Beta software that is not guaranteed to be stable, and therefore will not be supported by RIM or your wireless carrier should you run into some problems. As a precaution, if you decide to upgrade, it is highly recommended that you make a backup before using this software. If you are not comfortable using Leaked/Beta software you should probably wait for the next official release. *
