If you are a member of the BlackBerry Beta Zone in the Facebook 2.0 or BlackBerry Traffic programs you should head on over there. Both of the apps have been updated today with minor updates. The Facebook for BlackBerry update is only for OS 6.0+ devices but attempts to fix the issues users are having with signing in. The BlackBerry Traffic update to v18.104.22.1689 brings minor user interface fixes and miscellaneous bug fixes.
Here are the direct links to the programs if you need them:
Kudos to Nikolaus for the tips!
