Net Applications has released figures relating to mobile browser market share for February 2009. Apple’s iPhone, which accounts for about 0.5% of all cell phones, holds 66.61% mobile browser market share according to the findings, with its closest competitor Java ME (such as Blackberry handsets) at only 9.06% The actual results will likely begin to change as Microsoft rolls out its highly upgraded Internet Explorer browser and as Palm rolls out its Palm Pre with a revamped browser. Mozilla is also preparing to launch its own mobile internet browser dubbed Fennec. Interestingly, the Mac OS in February 2009 held 9.71% of the total computer operating system market share, down from 9.93% a month earlier in January 2009. The iPhone also generates 51% of all current U.S. mobile internet browsing traffic.
