The BlackBerry Beta Zone rolled out some updates this week to the two main social apps. Twitter for BlackBerry was updated to v126.96.36.199 with a bunch of fixes to @Mentions, options, and virtual keyboard. Facebook for BlackBerry also got some love bringing it to v188.8.131.52 which supposedly fixes a bug or two.
You can pick up both at www.blackberry.com/beta. Thanks to everyone who sent this in!
