Google today at last confirmed the Nexus S, the first phone to run Android 2.3. The Samsung device is the first to run Android 2.3 and is a showcase for some of its most important features: it now has a front-facing camera for video chat and other functions, NFC for short-range payments, and a full gyroscope for better motion control. It also has a unique variant of the four-inch Super AMOLED in the Galaxy S, the Contour Display, which reportedly has a more natural view than a flat screen.
