Facebook Messenger for iPhone and Android was released a couple of days back which is a standalone app for messaging to your Facebook friends and mobile contacts.
The app was released for iPhone and Android first, but according to the Help pages on Facebook,Facebook Messenger will soon be making its way to BlackBerry devices as well.
This app is a direct competitor to BlackBerry Messenger and WhatsApp (both of them used on BlackBerry a lot), and now Facebook wants to dominate that area as well.
