Microsoft Officially Kicks Off Sales of Windows Phone 8.1
Microsoft began selling the Nokia Lumia 630 today, marking the official availability and launch of Windows Phone 8.1. Both the Lumia 630 and Windows Phone 8.1 were revealed by Microsoft and Nokia during the former's Build developer conference in April. The 630 is for sale in Asia first, with Europe and the U.S. to follow. It replaces the Lumia 520 and will be sold as the Lumia 635 in the U.S. The timing of the Lumia 635's arrival in the U.S. is unknown at the moment. Windows Phone 8.1 adds a wide range of new features to Microsoft's smartphone platform, including the Cortana virtual assistant, space for more Start screen Live Tiles, and a notification center. Most existing Windows Phone 8 devices will be upgraded to Windows Phone 8.1 this summer, though a developer preview of Windows Phone 8.1 is available to download for free.
