Back in November, research firm Strategy Analytics estimated that Samsung's Galaxy S III had topped the list of worldwide smartphone shipments for the third quarter of 2012, taking advantage of a lull in iPhone 4S sales ahead of the iPhone 5 launch to claim the crown. Unsurprisingly, the firm's latest figures published today find that Apple easily reclaimed the title for the fourth quarter of the year with the iPhone 5 seeing shipments of 27.4 million units for 12.6% of the market.
