The Nexus S 4G is available for pre-order from Best Buy's website, meaning it can be yours without encountering a single smurf-shirted employee. Sprint's version of the Nexus S, now with WiMAX support, features a pure Gingerbread OS that's a perfect match for Google Voice. This Sammy sells for $199 with a two-year agreement, and while you're welcome to try your luck at a retail outlet, just be sure they don't give you T-Mobile's version. Of course we know the difference, but do they?
