Nokia Sold 6.6 Million Smartphones in Fourth Quarter, 67% of Which Were Windows Phones

Nokia shares surged 19% in trading today following a better than expected fourth quarter.

The company shipped 6.6 million smartphones, 67% of which were Windows Phone devices such as the Lumia 920. Not a real threat to Apple’s iPhone or Google’s Android, but certainly something that Research In Motion will feel threatened by as the two platforms battle for third place in the mobile OS space.

Nokia’s financials were also bolstered by $65 million in patent fees and a strongly performing Nokia Siemens Networks unit. The company managed to pull out a profitable quarter, despite forecasting otherwise.

However, although it’s riding a high, Nokia remains cautious and issued another conservative forecast for the first quarter of this year. It does not anticipate its handset division to be profitable.
