Cheaper phones are the key for Nokia and Microsoft in their battle to win a larger share of the market, analysts say. In addition to the new Lumia 610 Nokia will also unveil at the Mobile World Congress trade show in Barcelona a global version of its high-end Lumia 900 phone, which AT&T is scheduled to roll out in the United States, the sources said. Nokia is set to unveil the phones at a news conference next Monday, on February 27. Nokia last year dumped its own smartphone software platforms in favor of Microsoft's Windows Phone, which has so far had a limited impact due to the high prices of phones using it.
