Nexus S is the last terminal launched by Samsung (with Google) and with Android OS 2.3 Gingerbread. Samsung Hummingbird (based on the ARM Cortex A8 CPU), supported by 512MB of RAM and 16GB of space for data storage. The equipment is also supplemented by a 5-megapixel camera, Bluetooth, WiFi and NFC (Nier Feel Communication).
A white version of the Nexus S, the only device currently in possession of Android 2.3, has shown up in its first photos (as far as I know), courtesy of the good people at Phandroid via a German website called BestBoyz.
Surprisingly, Nexus S back in the last hours, thanks to the publications for some images of the white version. In this model, the front is black in color while the back is white.
