Nokia is now the major force in the Windows Phone 7 revolution with the Finnish company grabbing the largest market share for Microsoft's growing platform for the first time in the last quarter of 2011.
The figures, from Strategy Analytics, show that Nokia shifted 900,000 Windows Phone 7 handsets in October, November and December of last year - a 33 per cent share of a total sales figure of around 2.7 million. That figure represents a growth of 36 per cent for Microsoft's mobile OS from the previous quarter.
The boom is a result of Nokia going live with both the Nokia Lumia 710 and the Nokia Lumia 800 in November. Stephen Elop, the American CEO charged with getting the Scandinavian company back on track, stated at the end of last month that over 1 million Lumia handsets had been sold. This despite the fact that Nokia recorded an operating loss of €954 million, around £800 million, for the last three months of 2011.
Neil Mawston, executive director at Strategy Analytics, said: "An expanded portfolio of Windows Phone 7 models such as the Lumia 800, an increased retail presence and highly visible marketing campaigns across several European and Asian countries drove Nokia’s growth.
"Nokia is by no means out of the woods yet, and it is still on a long road to recovery, but capturing top spot in the Microsoft smartphone ecosystem is an encouraging baby-step forward for the company."
Nokia is expected to announce further Lumia devices at next week's MWC expo in Barcelona including a European version of the Lumia 900 that was shown off at CES, and possibly an entry level device going by the name of the Lumia 610.
