Nexus S is the first smartphone to feature a 4” Contour Display designed to fit comfortably in the palm of your hand and along the side of your face. It also features a 1GHz Hummingbird processor, front and rear facing cameras, 16GB of internal memory, and NFC (near field communication) hardware that lets you read information from NFC tags. NFC is a fast, versatile short-range wireless technology that can be embedded in all kinds of everyday objects like movie posters, stickers and t-shirts.
Gingerbread is the fastest version of Android yet, and it delivers a number of improvements, such as user interface refinements, NFC support, a new keyboard and text selection tool, Internet (VoIP/SIP) calling, improved copy/paste functionality and gyroscope sensor support.
