Windows Phone has updated their FaceBook page for the arrival of Mango, inviting folks to "Meet 7.5." The revamped page features a video tour of Mango by Beth Goza, Senior Manager of Windows Phone Marketing. The tour captures key concepts of WP7, such as People, Communications, Apps, and Internet. It goes over the basics of the Start screen, Live Tiles, social network integration, gaming, and the newly-empowered Bing. Nothing Earth-shattering here, but it's a nice introduction for those unfamiliar with Windows Phone and the upcoming Mango enhancements.
