According to stats from Chartboost, the market share of iOS 6 reached 30% after only 5 days released from Apple. And up to last week, there are 45.3% of iDevices running on iOS 6.
According to Chartboost, most of the iOS 6 runs on iPhone and follow by iPad and iPod Touch. We expect there will lower growth rate for iOS 6 due to the maps issue. Perhaps the maps mistakes deterred users from update their devices into the iOS 6. [Chartboost]
