If you want the details here are a couple of quotes from the Financial Times: “Shares in the world’s largest mobile phone maker fell 2.4 per cent to close at €8.70 after investors were disappointed by Nokia’s guidance for its handset business.” “Enhancing the attractiveness of Nokia’s smartphones is essential if the company is to raise the profitability of its handset unit, because the sophisticated devices generate a higher margin than basic handsets.” “The profitability of Nokia’s handset business has plunged this year, in part because of its struggle to produce user-friendly smartphones, and Mr Kallasvuo outlined efforts to remedy the situation.” “Nokia also said it would release a sophisticated smartphone based on a Linux operating system called Maemo in the second half of next year. It will be a successor device to the N900.”
