Beluga has been on the Android Market for quite a while and it has grown to become a very popular application as a BBM replacement for non-Blackberry devices. The application is well furnished, it also has the feature of group messaging, sharing photos.
There has not been any announcement either from Facebook or from Beluga about the future of the application there has not been any changes in the services of this application yet but maybe Facebook will be trying to integrate the location and photo sharing service to its mobile app which currently supports group messaging. We might be hearing official word about the advancement of this application in a few weeks.
