Yeah its a new app that facebook made. It bring all the messaging parts of facebook into one app(messages,chat). They did this because if you've ever used facebook on android you would know that it sucks in that aspect. However I don't see blackberry needing this at all because it handles messages and chat seemlessly.

i was thinking the same thing myself. the chat built into the FB app blows the iPhone and Android versions away. it looks very close to the normal full-desktop version.
The whole point is for your contacts to get your message no matter what so through either fb chat and if they're not online then it will text them your message but that contact has to have their cell number "registered" on their fb profile or else they won't be able to receive the message. Sounds like a reponse to iMessage to me.
