Market research firm Garter has released its latest report detailing worldwide smartphone market share, measuring by sales, covering Q1 2010.

The numbers reveal a clear winner in Google Android as its share of the smartphone market soared from 1.6 percent in Q1 2009 to a whopping 9.6 percent in in the same quarter this year. The 10.1 percent market share owned by Microsoft for its Windows Mobile operating system in Q1 2009 dropped sharply to 6.8 percent in Q1 2010, clearly marking the company’s difficulty in competing with the latest newcomers to the mobile operating system market as it prepares to launch Windows Phone 7.

Apple’s iPhone OS surprised no one with its numbers, jumping from 10.5 percent to 15.4 percent market share. Nokia and RIM continued to dominate the standings with market shares of 44.3 and 19.4 percent respectively.
