Samsung Galaxy S III dethrones iPhone 4S as smartphone sales champ for Q3 2012

The Galaxy S III has overtaken Apple's iPhone 4S for the first time ever to become the top selling smartphone for Q3 2012, according to Strategy Analytics. Samsung claimed the pole position by shipping 18 million copies of its flagship handset during the quarter, compared to Cupertino's 16.2 million iPhone 4S units. Of course, serendipity is also likely at play, as the iPhone 5 hit shelves towards the end of that period, likely cannibalizing 4S sales -- in fact, the market research firm thinks Apple's new top handset will likely trump Samsung in Q4. That means the Korean giant may have to step up its game, or it'll just be keeping the top spot warm for its arch-competitor. Check the PR after fold for more info.
