Continued strong sales of Apple’s blockbuster smartphone have propelled the Cupertino-based company into the No. 1 spot globally. As noted by the Financial Times, Apple shipped 20.34 million iPhone handsets last quarter, up from 18.7 million units in the first quarter of 2011. Meanwhile Nokia’s smartphone shipments dropped from 24.2 million units in the first quarter to just 16.7 million smartphones in the June quarter ā 3.64 million fewer smartphones than Apple. With just two smartphone models currently available for sale, Apple had already been the world’s top smartphone vendor by revenue and profits. The June quarter marks the first time the company has managed to out-sell Nokia by volume, however.
