The beta app will be available to a select group of users, before BBM goes live for all Windows Phone users.
BlackBerry has announced that the BBM for Windows Phone beta will kick off Thursday, with a limited group of users getting early access for testing the app.
BBM for Windows Phone was announced last week, and the app is already live in the Windows Phone app store. However, users will only be able to use it if they registered for the beta and are selected for the closed beta testing group. The registration program is currently said to be full, but BlackBerry expects to have more slots open in the coming days.
A release date for the final app is currently unknown. BBM for Windows Phone is expected to have the same features as its Android and iOS counterparts, including group chats and file sharing, but will be unique in that it will have an interface that follows Windows Phone design guidelines, which should set it apart from the version on other platforms.
