When it comes to smartphone market share in the United States, the BlackBerry is still king of the hill according to a recent report by comScore, however, Android is coming on strong.

For the three month period ending Feb. 10, RIM’s percentage of market share was 42.1%, up 1.3% from the same period a year earlier.  Android is still just a fraction of the total smartphone market at 9%, however, they were the only other platform to actually increase share, up 5.2%  year over year.  Apple remained relatively flat, down 0.1%, and Palm and Microsoft lost share, with -1.8% and -4.0% drops year over year.

It will be interesting to the comScore report for the three month period ending May.  Android should still be on the rise , Apple should still be flat, Windows should still be a dog.  The big questions for me are will you see RIM take a dip and will Verizon’s webOS campaign turn Palm positive?
