RIM’s hugely popular BlackBerry Messenger service looks set to be rolled out across rival devices with screens of a BBM app running on Android making a premature appearance.

The screens, which were sent to T3 via an anonymous source, show a Beta model of the free to use instant messaging service running on an unspecified Google Android OS powered handset, adding meat to the formerly speculative rumours that BlackBerry is to bring its BBM service to Android and iOS devices in the near future.

BBM for Android Release Date

Currently available exclusively to BlackBerry handset owners, the much loved BlackBerry messenger service is, according to our internal source, on its way to rival handsets with the BBM for Android app currently in the “final stages of testing.” Further teasing the service’s more widespread availability they added “it should be out by 2012.”

BBM for Android Features

Whilst we are still uncertain exactly what guise BBM for Android will take, it is expected the app-based service will be free to download and play host to the same functionality bestowed upon BlackBerry handset users.

The source responsible for the leaked images added: “I'm afraid there isn't really much more I can tell you apart from it seems to work quite well with Android's push notifications.”
