As we heard they’d do earlier in the week, RIM went ahead and released the newest version of Facebook for BlackBerry. It brings plenty of changes, including a new, sleek user interface, native Facebook chat, and tons of other features, including BBM integration. There’s a full breakdown at Inside BlackBerry, where you can get some neat-looking screen shots. Make sure to watch the video above, too, for an excellent walk-through of the newest features. If your phone doesn’t automatically update, you can download Facebook for BlackBerry from App World. You’ll need OS 5 or better. If you have a PlayBook, you can download that version here.
