As expected, Samsung unveiled different variants of its flagship Galaxy S II Android smartphone for AT&T Mobility (NYSE:T), Sprint Nextel (NYSE:S) and T-Mobile USA. Also as expected, Verizon Wireless (NYSE:VZ) was not part of the party. The strategy mirrors Samsung's approach to the original Galaxy S, introduced last year, which eventually wound up being sold by virtually all of the nation's wireless carriers. Sprint was the only carrier to disclose pricing and availability of the Galaxy S II. Sprint's variant, dubbed the Epic 4G Touch, will support WiMAX and will be available for $200 with a two-year contract starting Sept. 16. Slideshow
