Ad network and analytics firm Chitika claims it has seen no significant increase in iOS 6 adoption in the U.S. and Canada. A company analyst believes the MoPub data (which was international, rather than domestic) we wrote about earlier today was affected by the recent launch of the iPhone 5 in China, rather than the release of Google Maps. This past weekend, Apple issued a press release bragging that it had sold more than two million iPhone 5 units in China over the first three days of availability. In the chart above -- which only looks at data from the U.S. and Canada, rather than the international data that MoPub examined -- the iOS 6 adoption slope following the release of Google Maps for iOS remains practically unchanged from before the release, suggesting a sea change in iOS 6 adoption rates resulting from Google Maps release is inaccurate. Chitika Data Solutions Engineer Gabe Donnini: On Monday, Google reported that Google Maps for iOS had been downloaded more than 10 million times.
