Nokia just released an eight-minute long video documentary discussing the decisions behind the company’s “first Windows Phone,” with Nokia calling it “as much a story about collaboration and taking risks as it is about design.” The Lumia 800 runs Windows Phone 7.5 (Mango) and will be widely available across key markets worldwide.

We go behind the scenes at Nokia’s London design studio with Stefan Pannenbecker, VP of Industrial Design at Nokia, Chris Linnett, Head of Lumia UX design and Kate Freebairn, Creative Director for Lumia UX design to explore the story behind the creation of Nokia’s first Windows Phone.
