comScore released its December results survey and Apple had its eleventh month of increased market share when tabulated on a three month rolling average.  Apple had a 36.3% smartphone market share for the last three months of 2012 and increased its share by 6.7 percentage points over the past year.  Not surprisingly Android has the leading smartphone market share at 53.4% and increased its take by almost as much as Apple.  RIMM (now Blackberry) lost a large amount of share, almost 10 points for the year.  Microsoft continues to slip so the race to become a worthwhile third platform is still anyones game.
