Although not official yet the BlackBerry Messenger is going to get an update soon. The PIN-based messaging system will get some important upgrades like: Avatar support, GPS location integration, Proximity sensor, Homescreen support and Set conversation subjects.
In other words you can now set your own avatar picture just like you would do in other instant messaging apps. Friends will be able to see you on the map and you will also know if you’re close to each other that’s going to be obvious too. All we need to do now is wait for the messenger update to be available!
