Windows Phone 8

Microsoft said during a press event in San Francisco that its newest Windows Phone 8 mobile operating system will ship this holiday season. It will feature a "shared core" with Windows 8, which means the devices will have some sort of similarities. The company is still explaining exactly what that "shared core" means and we'll keep you updated. Windows Phone 8 will support NFC, a new Wallet technology for mobile payments, microSD cards, new security features and new display resolutions. Microsoft said it will be available "this fall" but also said devices will ship by the holiday season.
