Now that most Windows Phone devices are running Mango the floodgates on Tango rumors have started, Tango was previously rumored to be released sometime Q2 of 2012, which isn’t too far off now. The latest batch of rumors claim that Tango will enable users to add ‘Folder Tiles’ to your own live homescreen; making it easier to access your apps directly. The second rumored change is the reduction of the size of the playback buttons while watching videos/movies. Of course Tango isn’t as massive of an update as Mango was but it’s sure to iron out some of the wrinkles left in WP.
