Nokia unveils first Windows phones
It could also mark a turnaround for Microsoft's unpopular Windows Phone 7 software.
Nokia CEO Stephen Elop unveiled the company's new partnership with Windows Phone 7 today in the form of the Nokia Lumia 800 - a hi-tech, mid-priced handset running the latest version of Microsoft's operating system.
The phone costs £364. The cheaper, lower specced Lumia 710 model will cost just £234. Both will go on sale across Europe in November.
The pricing in particular could be crucial in putting Microsoft's Windows Phone 7 back in competition with its smartphone rivals.
Microsoft CEO Steve Ballmer said that the Windows giant would cut prices to drive sales.
