Internally, there's no difference between the HTC One S that was announced at Mobile World Congress and the black One S that's available as of right now on T-Mobile.  The biggest difference comes in color; while the black one was available worldwide from the start, T-Mobile's just getting the unit now.  Featuring a finish that's a result of a process called microarc oxidation (MAO), the One S is a great choice this holiday season.  Better yet, it's free!
