<< Recently, we introduced Nexus S from Google, the first phone to run Android 2.3, Gingerbread. In addition to the UMTS-capable Nexus S, today we’re introducing Nexus S 4G from Google, available for Sprint. Nexus S 4G is part of the Nexus line of devices which provide a pure Google experience and run the latest and greatest Android releases and Google mobile apps.

We co-developed Nexus S 4G with Samsung to tightly integrate hardware and software and highlight the advancements of Gingerbread. Nexus S 4G takes advantage of Sprint’s high-speed 4G data network. It features 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 everyday objects that have NFC tags. >>
