Earlier today, a BBM beta has shown itself in the Windows Phone app store with the following description:

“BBM for Windows beta. We’re getting ready to welcome Windows Phone users to the BBM community. BBM brings you together in the moment with friends and family through instant chats, voice calls, picture sharing, voice notes and more.”

We’ve known for awhile now that BlackBerry would be bringing BBM to Windows Phone users after it successfully rolled it out to iOS and Android customers.

The BBM beta for Windows Phone is listed as compatible with Windows Phone 8 and 8.1. However, it is in private beta, which means you might not get your hands on it just yet.

“We have been using the Windows Phone storefront to help conduct a closed internal beta to test the BBM for Windows Phone app. We plan to use the Windows Phone store to facilitate a broader external beta in the coming weeks. Only users who have been whitelisted to participate in the beta will be able to install the app. More information on how to participate in that external beta will be available through the BBM blog shortly,” said a BlackBerry spokesperson to CNET.
