Apple’s latest iPhone operating system, iOS 4, has been available for just over one month now, and already it has managed to edge out the previous operating system, according to online ad network Chitika.
The company reports that iOS 4 leads iOS 3 by just 1%, with 50% of all iPhones running the new operating system.
The report, which comes from a survey of more than 9 million iPhone impressions across Chitika’s advertising network, shows that 49% of phones still run on iOS 3, and a tiny fraction – that 1% difference – still run on some archaic version of iOS 2.
Chitika offers a closer look at the numbers to show that only 5% of iPhones are running the latest update of iOS 4, and a third of those still running iOS 3 are not running the latest version of it.
While we expect that some of the iPhones running iOS 3 are doing so because iOS 4 would slow their phone down (as has been reported with the iPhone 3G), we also suspect that a percent of phones have not updated to keep their jailbreak intact. It would be interesting to see what happens to these numbers when a reliable way is found to jailbreak iOS 4 for the iPhone 3GS.
