Although it's no longer there, Best Buy published an ad for the “Nexus S for T-Mobile” and displayed that it would have a “pure Google” experience. In addition, it was stated that Best Buy would be the exclusive seller for the handset, but unfortunately, it was quickly removed from their site.
Naturally, news about the Nexus Two began to swirl around and spread like wildfire – even going as far as saying that Samsung would indeed be the manufacturer for it. And when you think about it, there could be a correlation between the “Nexus S” and Samsung. Nevertheless, the speculations are all still out there with even the notion of whether or not the successor to the Nexus One will eventually come to fruition.
