Windows Phone 7 Icons...

In mid-March 2010, Microsoft unveiled Windows Phone 7 to the world. In late March 2010, Microsoft made some of the icons associated with Phone UI available here.

This package includes three different versions of the icons: light, dark, and vector. Each version provides 32 of the core icons used throughout the Windows Phone 7 UI.  These provide a great way to prototype the mobile applications you want to deliver to the world.
