Nokia's Symbian is still the largest smartphone platform by a wide margin, but it's not growing as fast as the competition. The company moved 24.1 million units, up from 17.8 million a year earlier, but its share slipped from 48.8% to 44.3%. Meanwhile, Research In Motion took the second spot dropping from 20.6% to 19.4%. In terms of actual phones, not just smartphone platforms, Nokia remained atop while RIM was fourth and Apple climbed to No. 7.
Overall, worldwide smartphone sales reached 54.3 million units during the fourth quarter, up a whopping 48.7% year-over-year. By contrast, mobile phones in general grew only 17% to 314.7 million units.
