BlackBerry 10 is on life support, with few sales and fewer devices. It's in such a bad state that the company has switched its attention to Android, giving developers little reason to support its own operating system. Facebook jumped ship earlier this month, announcing that it would end support for its apps later this year. But wait! BlackBerry has announced a new, replacement Facebook app. Unlike the old one, however, it's just a web app. That does mean a few extra features, such as the ability to reply to comments (yes, really), but it's far from a like-for-like swap.
