About BlackBerry Messenger 
You can use BlackBerry® Messenger to chat with your friends who have a BlackBerry device. You can send messages, voice notes, and even contact attachments to your friends. If your device has a camera, you can also send pictures as soon as you take them. Like a lot of other social networking applications, you can also set a status to keep your friends updated on where you are and what you are doing. You can find the BlackBerry Messenger icon on the Home screen or in the Instant Messaging folder.
