Galaxy S II. Or is it Galaxy S 2 Attain? Perhaps it's Galaxy S 2 Function or Within, it all depends on what carrier you prefer, really. You see, the sleuths at Pocketnow have unearthed a silicone case for sale that lists those three names as the particular branding Samsung's new flagship smartphone will enjoy with AT&T, Verizon and Sprint, respectively. That, combined with earlier trademark filings by Sammy asking for Galaxy Attain, Function and Within registrations, would lead us to believe that we are indeed looking at the final product monikers. T-Mobile is notably missing from the list, but we suspect that may be because its variant of the Galaxy S II is materially different in design to the original GSII. The good news for everyone else is that the same silicone case will be interchangeable among AT&T, Verizon and Sprint devices, leaving very little room for those guys to screw things up.
