Cliff Simpkins, PM of Windows Phone division, posted a detail article regarding the refreshed beta announcement, changes for developers and lot more. Read the official blog post here.
Tom Warren of Winrumors posted his hands on experience with Twitter integration in Mango. It works just as expected. See the integration below in action:
