BlackBerry is rolling out a new update to their BBM beta program this afternoon. The update brings the addition of sponsored content and invites. As we reported earlier, the BBM team was testing ads on Android and iPhone users, and it seems now the BlackBerry side of BBM will be getting the test as well.

The new beta also increases the attachment size limit to 16MB for BlackBerry 10 users. BlackBerry OS  users do not get an upped limit for sending files with this beta. Q10/Q5 owners will notice a nice little change in the UI with Stickers on BBM that makes it a little easier to use.

If you’re one of the lucky ones in this limited beta, check out the Beta Zone app for the update.
