Smartphone sales rose to 54.3 million units in the first quarter of 2010. This marks an increase of 49 percent over the same period last year, the biggest sales jump for smartphones in four years.

Also, Google’s Android OS equipped phones outsold Microsoft’s Windows mobile phones for the first time, taking nearly 10 percent compared to 6.8 percent for Windows mobile. Android has also overtaken the iPhone in the U.S. market.

Nokia’s share for the Symbian fell from 48.8 percent to 44.3 percent. RIM’s Blackberry saw a slight drop, going from 20.6 to 19.6 percent.

Nokia and Microsoft have delayed the launch of their new smartphones until later this year, a move that might cost them precious market space.
