Facebook tweeted today that they have updated their Facebook app. What Facebook also sneakily did was release an official version for BlackBerry users. The BlackBerry version brings the same features as found on iOS and Android (which were supported when the app first launched).

Now you can see who’s online and who’s on mobile, and know when the other person is typing. It’s also easier to send messages to the people you message most.

With this update, the app is now available for BlackBerry in addition to iPhone (including iOS 5) and Android. We’ve also added support for 22 new languages for Android, and 12 new languages for iPhone.

If you’re psyched about keeping in touch with your Facebook friends, you can download the new app by pointing your BlackBerry and clicking the OTA link here.
