I guess the statistics are not for those who have received FROYO officially, like those overseas. If the chart is only for the U.S. Galaxy S owners then the statistics are stunning, I had no idea that so many people already did the R&R to their cells!
This is for all Android devices that have accessed the Android market so I assume it is a world-wide sampling. A breakdown of U.S. phones only would be interesting though.
