It’s always nice to have an external Facebook chat client to turn to, without needing to run the actual Facebook app. For BlackBerry users, A+ Chat for Facebook might be the most convenient one to turn to. The UI is designed to resemble BlackBerry Messenger, and retains all the functionality of native Facebook chat. You’ll also receive popup notifications when you receive incoming messages while the app is running in the background. You can also get profile pictures next to your friends’ names, and can set available or idle statuses. Finally, it works with auto-text, which is always a nice time saver. It’s available right now from BlackBerry App World on sale for $0.99.
