Staying true to its Galaxy S forefather, the Nexus S has shown up with a new white shell, which, just as with the Galaxy S, only extends to its rear portions, leaving the front end a familiar shade of noir. Just what's keeping manufacturers from blanching their phones' visage, we don't know, but at least it's looking like there'll be some variation in the Nexus S' palette. We did notice a "Silver Black" Nexus S sprouting up in European retailers' listings a couple of weeks ago, which this could well be -- it all depends on how loosely these companies define the word "silver." There's no knowledge on when or where this chromatically altered S will be on sale, but you'll know more as soon as we do.
