BlackBerry Messenger

BlackBerry Messenger (BBM) is a proprietary Instant Messenger application included on BlackBerry devices. It was developed by Research In Motion (RIM), maker of the BlackBerry device. Messages sent via Blackberry Messenger are sent over the BlackBerry PIN system; thus, communication is only possible between two BlackBerry devices. Exchanging messages is also possible via dedicated discussion or chat groups, which allow multiple BlackBerry devices to communicate in a single session. In addition to offering text-based instant messages, BlackBerry Messenger also allows users to send pictures, voicenotes (audio recordings), files, location on a map, and a wide selection of emoticons (also known as "smileys") over the Blackberry network. Blackberry messenger allows you easy access to keeping in touch with friends by instant messaging, and you can create a profile that can be updated as much as you want sort of like a social network on your mobile phone. With the release of BlackBerry Messenger 5.0, BlackBerry allows users to use a QR Code barcode to add each other to their respective friends lists rather than using only numeric PIN identification or an email address associated with the user's BlackBerry.
