BlackBerry may be the struggling for relevancy in 2014, but they still have a couple of valuable properties, including their BlackBerry Messenger (BBM) service, which is now on iOS and Android. Earlier this year, BlackBerry announced that a version for Windows Phone was also on the way, and July was last reported as the due date.

With that introduction, it should not be surprising to find the private beta of the app hiding out on the Store under the BlackBerry Limited publishing name. However, like all good things, you cannot download it yet. Private beta means you have to be on the tester list, and that involves using your Microsoft Account ID. As a result, you can look at the app on the Store, but you can not download.
