Nerval's Lobster writes "Last week, research firm IDC issued a report suggesting that Windows Phone shipments exceeded those of the iPhone in seven countries around the world, including Argentina, India, Poland, and Russia. The data startled some people — Daring Fireball's John Gruber, for example, blogged his skepticism. As the story gained a bit more momentum, The New York Times' Nick Wingfield reached out to IDC analyst Kevin Restivo for a bit more clarification: 'IDC's numbers also reflect only the official number of cellphones imported into the countries,' he wrote. 'Mr. Restivo said that in some countries, like Argentina, high government taxes mean there is a very significant gray market in cellphones, which IDC doesn't track.' Now new survey data from Kantar Worldpanel uggests that Windows Phone is indeed gaining some sort of momentum in some parts of the world: Android was responsible for 51.2 percent of smartphone sales in the U.S. for the quarter ended February 2013, followed in second by Apple's iOS with 43.5 percent, with Windows Phone edging up into third place with 4.1 percent. BlackBerry trailed in fourth with 0.7 percent, down significantly from its 3.6 percent market-share last year. That doesn't mean that Windows Phone will prove any sort of champion in the near term, but maybe the platform isn't totally on life support."
