The Nexus S is going for about $450.
$200 with a two year contract.
There are only a few differences between a Nexus S and a Nexus S 4G. Nexus S is T-Mobile phone, while the Nexus S 4G is a product of Sprint's Samsung. The only other major difference is that the 4G version offers Google Voice.
Nexus S was created on 2010-12-16.
It never did, but it did get the Galaxy Nexus, which had a number of improvements over the Nexus S.
The Google Nexus S is from T-Mobile and Sprint.
The Nexus S 4G is a CDMA phone and the Nexus S is a GSM Phone. This is the basic difference between these two phones. Most of the remaining configurations are same.
The Nexus S came in both CDMA and GSM variants.
The Nexus S is no longer manufactured. The newest Nexus phones can be bought and used on the Sprint network.
The Samsung Nexus S was an evolution of the original HTC Nexus One's design and hardware. The Samsung Galaxy Nexus was a leap forward from that design, going with a significantly larger display, better chipset and CPU/GPU, a much improved design, and was arguably the first widely commercially-available and advertised Nexus device.
The Nexus 4g is the best version of this phone. It has improved so much since the first model. It has all that you need in a phone. Fast, Reliable, and has great service.
It was manufactured by Samsung.
No
If you can manage to get an unlocked GSM version, that could be possible. I believe that for a brief period, AT&T did carry a Nexus S.
