Samsung's Galaxy S II celebrates 20 million sold, just in time for MWC

After crossing the 10 million units moved threshold back in September, Samsung has joyously announced ahead of MWC 2012 that its Galaxy S II family of phones has sold 20 million since launching in April. According to Samsung, taking just ten months to hit the mark puts it ahead of the original Galaxy S (hovering around 22 million sold) by seven months. The hallmarks of this model -- in its many forms as seen above for AT&T, T-Mobile and Sprint -- has been the Super AMOLED Plus screen, slim design and dual core CPUs, all of which made it a record breaker right out of the gate. Samsung's been pretty quiet as Mobile World Congress 2012 approaches, but whenever we see the Galaxy S III, it will certainly have a lot to live up to.
