BlackBerry OS usage in July was mostly unchanged from last month. Use of OS 6 was up to 29.9% while use of OS 5 or higher was up to 87%.

I would expect a big bump in both of these numbers next month, as they begin to be propped up by the sale of OS 7 devices.

This data was taken from downloads of the popular BlackBerry strategy game Pixelated. Data is from the beginning of July 2010 through the end of July 2011.
