It seems that Android is continuing to increase their market share, at least according to numbers for Mobile Web Consumption for the month of August. As seen in the graph posted above, Android continues to rise, while iOS and RIM both continue to fall.
The numbers also look good in the chart posted below, which measures changes for the month, quarter, and the entire year. Now granted, these statistics are pulled from Mobile Web usage, not from actual vendor numbers, which will give a much better idea of how Android is continuing to fair in the Mobile OS market. Quantcast will have those figures next week, so stay tuned.
