at BlackBerry's 2010 Developer Conference last fall, BBM Social Platform has just become available to interested third-party devs in beta form. Of course, you might be hoping that it opens BlackBerry Messenger to other (read: non-BlackBerry) platforms via API... but yeah, that's not happening quite yet
. Instead, the SDK allows folks developing for BlackBerry OS to integrate BBM capabilities into their own apps, and the list of capabilities is pretty extensive: you'll be able to read and update user profiles, embed BBM chats inside your app, and transfer files, just to name a few of the big ones (with the user's permission, of course). The current beta works for Java apps, while RIM's hard at work crafting a new version for release in April that'll add WebWorks web app compatibility.
