Fresh evidence emerged Thursday that Windows Phone has steamed past BlackBerry to establish itself as the world’s No. 3 smartphone OS. New data from Gartner shows that Windows Phone sales hit 8.9 million in the third quarter of 2013, more than doubling the roughly 4 million Windows Phones sold in Q3 2012. Over the same period BlackBerry sales crashed and burned, plummeting from 8.9 million in Q3 2012 to 4.4 million in Q3 2013.
