Microsoft Corp.'s flagging Windows Phone 7 software got a boost this month when Nokia Corp. agreed -- in return for billions of dollars -- to run the operating system on its next generation of mobile phones.
Nokia CEO Stephen Elop said the phone maker selected WP7 over Google Inc.'s popular Android open-source software to ensure "a three-horse race" between Windows Phone, Android and Apple Inc.'s iOS in the mobile operating system market.
Observers had speculated that the deal would cost Microsoft millions or tens of millions of dollars. But the figure may be 10 times higher: Elop said at the Mobile World Congress (MWC) in Barcelona last week that "the value transferred to Nokia is measured in B's, not M's."
