Nokia only recently entered the Windows Phone market with the introduction of the Lumia 710 and the Lumia 800, but it's already the top seller of Windows Phone devices worldwide. That's impressive, considering the phone maker was beat to the market by other manufacturers such as LG, Samsung and HTC, which all released phones running the first iteration of Windows Phone 7. It's even more impressive if you consider that its brand new flagship Lumia 900 smartphone has yet to hit store shelves.

According to research firm Strategy Analytics, Nokia sold 900,000 of the total 2.7 million Windows Phone devices sold during the fourth quarter of 2011. That figure represents a 33% share of all Windows Phone sales. "Microsoft smartphone shipments remain tiny, but they are showing tentative signs of growth," Alex Spektor, associate director of Strategy Analytics said Friday. "Nokia overtook HTC and others to become the world's largest Microsoft smartphone vendor… as distribution of its Lumia family expanded across numerous countries and operators."

Strategy Analytics attributed the growth to solid marketing in Europe and Asia and an expanded portfolio of devices, The Wall Street Journal said. Nokia recently unveiled the Lumia 900 for AT&T during CES, which is already among our favorite Windows Phone devices. The company is also expected to launch a new Lumia 610 device for emerging markets during Mobile World Congress next week, and might launch an international version of the aforementioned Lumia 900 flagship, too.
