Galaxy S II’s launch in USA has been seemingly confirmed by the invitation. However, one thing that remained unconfirmed was Galaxy S II’s design, until now, that is. The promo video posted by Samsung touts the global success of Galaxy S II but its the end reveals the US-centric Galaxy S II design. Just as Samsung did for Galaxy S, Samsung has given away its physical Home and two touch-sensitive buttons found in the international version for four touch-sensitive buttons. Samsung will announce Galaxy S II on August 29 at an event in New York.
