Three years ago I was lucky to join the Windows Phone team at a time when we were “resetting” our approach to mobile operating system software. We made big changes to our design, our approach to partners, and our platform. The result was Windows Phone 7.
Now it’s time to start telling you about the next exciting chapter of our story: Windows Phone 8. Officially announced this morning in San Francisco, it’s the most advanced mobile OS Microsoft has ever made and will arrive on new phones later this year.
