Heads up, BB10 users: your Facebook app is in need of an update. As in, there's one waiting for you. Facebook v10.2.1 for BlackBerry 10 adds Facebook Chat, enhanced message details, quicker scrolling while in Newsfeed and an "enhanced photo experience." Moreover, you'll find added Page Admin functions as well as a "refreshed look and feel to your Pages." Naturally, the update is being provided for free, and can be picked up in the Appworld right here. Of course, it's also sporting a sterling 2 out of 5 rating, so hopefully the new features will go a ways toward improving the aforesaid mark.
