Was there pent-up demand for a downloadable Google Maps app for iPhone? Just a bit: according to Google, the app was downloaded more than 10m times in the first 48 hours after its release earlier this month.

That’s likely 10m iPhones with the Apple Maps icon now nestling in a Junk apps folder, although as TheNextWeb points out, 10m handsets is only around 2.5% of all iOS devices sold so far.

Elsewhere, advertising network Chitika has been trying to dispel suggestions that there were lots of iPhone owners refusing to update their software from iOS 5 to iOS 6 until the Google Maps app was available – iOS 5 being the last time a previous version was preloaded, rather than Apple Maps.

“When Google Maps for iOS was released at midnight ET on Dec. 13, devices running iOS 6 accounted for 72.77 percent of traffic on the iOS network. As of 2:24 PM on Dec. 14, iOS 6 traffic grew to 72.94 percent, an increase of just 0.17 percent,” explains Chitika.
