New Kantar Worldpanel data from Tuesday has shown Windows Phone overtaking Symbian in the UK. Although both were now small, Windows Phone was up to 2.5 percent of the British cellphones sold in the three months leading up to mid-February where Symbian had dropped to 2.4 percent. Much of that could be credited to the Nokia Lumia 800, which in Europe made up 87 percent of all Windows Phone sales.
