A new BBM beta has been launched today in the Beta Zone for BlackBerry 10 users. This latest build adds a pretty cool new feature that lets you chat on BBM with email contacts that you don’t have as BBM Contacts.

BlackBerry explains it this way:

“Chat with people outside of your BBM Contacts! Chatting with new friends is even easier. This new version of BBM allows you to send and receive messages with email contacts in your address book that are not yet BBM contacts. You’re always in control – these “extended” contacts won’t be able to see your profile picture or status updates until you add them as a BBM contact – which can be done easily with the push of a button.”

Now before you try to start chatting away with contacts that you don’t have on BBM, there is one limitation: both you and the recipient must have the latest beta installed to take advantage of this feature.

Once you load up the latest beta you’ll be able to see if any of your email contacts have this latest beta installed, and you can message them away.
