The Windows Phone Team held a party yesterday in NYC to celebrate the launch of new Mango and the new Windows Phones.

The event included a six story tall Windows Phone complete with live tiles!  One of my teammates, Peter Laudati, was on the scene and took plenty of pictures you can check out here.  The Windows Phone Team also has a post detailing the event here.
