Windows Phone 7 is released to manufacturing

Microsoft announced that the highly anticipated Windows Phone 7 mobile operating system has been released to manufacturing on Wednesday, a major milestone for the project.

Following the release of its developer toolkit, Microsoft released Windows Phone 7 technical preview to its developer, carrier and manufacturing partners in July. Since that time, the mobile OS has been updated in a number of ways, such as including intelligent Facebook contact filtering (only real friends show up,) and the ability to "like" Facebook posts from within the People Hub.

"Windows Phone 7 is the most thoroughly tested mobile platform Microsoft has ever released. We had nearly ten thousand devices running automated tests daily, over a half million hours of active self-hosting use, over three and a half million hours of stress test passes, and eight and a half million hours of fully automated test passes," said Terry Myerson, corporate vice president of Windows Phone Engineering on Wednesday. "We've had thousands of independent software vendors and early adopters testing our software and giving us great feedback. We are ready."
