During the (public) keynote, Tim Cook threw up a statistic that didn't seem to make sense to me.
He said that 93% of iOS users were on the most current version (which is iOS 6).
But a good number of iOS devices don't support anything greater than 5.1 (iPhones 3G or earlier, iPod Touches 3rd Gen or earlier and iPad first gen). So it seemed unlikely to me that 93% of iOS devices are running iOS 6.
Is there a reliable resource that lists what the device breakdown is among the public and visually impaired users?
I'm trying to decide how low-end a device I should support; currently, we don't support iPhone 3G or earlier or 1st/2nd Gen iPod touches. Apple makes that a convenient cut-off point.
