There is something interesting happening with BlackBerry (BBRY), which does not line up with the conventional wisdom. For the three months ended June 30, 2013, StatCounter shows BlackBerry with just 2.8% of the North American smartphone market share (base on web usage data). Apple (NASDAQ:AAPL) pretty well owns the market with 52.0% and Samsung takes the Bronze medal (click to enlarge)with 18.1%. There is nothing too surprising there.

Roll ahead to the third quarter, still under way. Now the picture is somewhat different. Apple share has dropped a bit to 50.9%, call it virtually unchanged within the bounds of measurement. Samsung is up a bit at 18.8%, again virtually unchanged but with a positive bias.
