How's Samsung's flagship smartphone, the Galaxy S II, doing these days? Pretty damn well! Even though it just recently launched in the States on Sprint and hasn't even arrived yet on T-Mobile and AT&T,  the "super phone" has already sold upwards of 10 million units, thanks in large part to several-month headstart overseas.

Samsung has already announced a slew of Galaxy S II spinoffs in recent weeks, including a new HD LTE version. The device will be available on AT&T on October 2 and on T-Mobile October 12. Read our review of the Sprint version, the Epic Touch 4G, here.
