The Windows Phone Dev Podcast unearthed some seemingly legit Windows Phone 7 screenshots last week that revealed a few new features apparently headed to the mobile OS, and it's now back with another batch that show yet more additions said to be included with the so-called "Mango" update. That includes support for Facebook Chat and Office 365 (plus SkyDrive and SharePoint), as well as a revamped Games hub that suggests even more Xbox Live integration (including a rather interesting new "Automatic Sync" option). What's more, the lock screen will apparently now show the album art if there is a song currently playing, and it seems there will be some new group messaging options as well. Of course, all that's still unconfirmed by Microsoft, but you can judge all the screenshots for yourself at the link below.
