The Facebook for BlackBerry app is already pretty good at letting you update your status, view your friends’ walls, and peruse through the uploaded pictures. How about Facebook chatting? That feature isn’t available as of yet, but while randomly browsing through the application permissions within Facebook, a BlackBerry user found a slot that asked for permission to use the integrated instant messaging service, which doesn’t exist. Does that mean an update is on the way to add the IM feature? Considering that RIM already has IM clients in place for various other protocols, and third-party IM clients can connect to Facebook Chat, I don’t see why RIM couldn’t do the same.
