Apparently BlackBerry smartphone users who are not running OS 5.0 are experiencing problems with downloading, and one of the major concerns when using a leaked OS 5.0 version is that most Research In Motion designed apps are not compatible reports Crackberry.
Of course this includes Facebook; however, almost too quietly, Research In Motion has updated Facebook to 1.6.0.22 which actually brings compatibility.
Therefore if you happen to be running a leaked version of OS 5.0 and haven’t been able to use Facebook, grab hold of this latest update and Facebook fun will all be yours.
