Back in April, Microsoft unveiled that it was working on a massive Facebook for Windows Phone update which finally went online today! While the Windows Phone OS itself can already interact with Facebook, the stand-alone app has more features and looks and feels more like the web version. However, a couple of important features were missed so far which Microsoft has finally added to v2.5. For instance it's now possible to like comments, the app shows full-threaded Facebook messaging including group messaging, allows to tag friends using "with" and "at" formats, delete posts and comments via long press context menu, supports active links in posts.
Last but not least, the update brings changes to the photo comments and likes page which means that the photo comments and likes page get an update to match the posts comments and likes page. Like before, this app isn't featuring Facebook chat but this is part of the Windows Phone Messaging hub and there's no reason to have it retundant again.
Facebook v2.5 for Windows Phone is now available free of charge from Microsoft's Windows Phone Marketplace but don't forget that you need at least Windows Phone 7.5 to be able to update your Marketplace apps from now.
