Apple's iOS 7.0.6 had captured more than 13 percent of all North American iOS traffic on the Chitika ad network just two days after its debut.
Releasing its findings on Wednesday, Chitika noted that the latest version of iOS accounted for 14.5 percent of ad impressions on the iPhone and 12.3 percent on the iPad, resulting in an average of around 13.3 percent.
Though the initial two-day adoption rate of iOS 7.0.6 failed to match the results for iOS 7, Chitika believes the majority of iOS users could be running the latest update within the next week. iOS 5.1.1, which also delivered a security patch, took around three weeks to reach a 58 percent adoption rate on the ad network. Chitika expects 7.0.6 to reach that number in a shorter period of time.
Apple pushed out iOS 7.0.6 on February 21 specifically to fix a security hole that would allow an attacker to access and modify data supposedly protected by SSL (Security Sockets Layer). The urgency of the update and the relatively ease at which iOS uses can install it directly from their devices likely led to its quick adoption.
iOS 7.0.4 is still tops among iOS devices with more than 50 percent adoption, according to Chitika's data. iOS 7.0.6 and iOS 6.0 were about neck and neck at the time of Chitika's study. By now, 7.0.6 should be firmly in second place and climbing.
