The Sprint version of the Nexus S shares a lot of similarities as the GSM model, including the contour 4-inch Super AMOLED touch screen, 1GHz Hummingbird processor, and NFC chip. However, one key difference is that this phone adds support for Sprint's 4G WiMax network. You can also use the device as a mobile hot spot, which costs an additional $29.99 per month but there is no data cap.
