Nokia today raised concerns of growing problems in its summer quarter's results despite improving its fiscal stance. The company's revenues were up five percent to the equivalent of $14.4 billion and returned back to a $565.3 million profit after a loss a year ago, but it now expected to lose market share for all of 2010 where it had insisted it would hold its position for most of the year. The warning came in spite of smartphone sales spiking year-over-year by 61 percent, to 26.5 million, and its total phone numbers climbing a small two percent to 110.4 million.
