According to the latest research released by IDC, worldwide smartphone shipments increased 89.5 percent year-over-year in the third-quarter of 2010, to 81.1 million units. While Nokia continues to hold the top spot in the worldwide smartphone market with 32.5 percent of all shipments, Apple’s Q3 shipments of 14.1 million iPhones — good for a year-over-year unit shipment increase of 90.5 percent — were enough to vault it past BlackBerry maker Research In Motion (RIM) into second place with a 17.4 percent share of the market. RIM ranked third with 15.3 percent of the market, followed by Samsung with 8.9 percent, and HTC with 7.2 percent.
