Apple reportedly charges $10 cpm and $2 cpc for iAds

"Apple has also introduced more flexibility to a pricing structure that had befuddled advertisers, ad executives say. Instead of charging marketers every time a user taps on an ad—a policy which often led to ad budgets quickly being exhausted—Apple is willing to put a cap on what it charges for the taps, according to the person. Advertisers pay $10 every time an ad is viewed a thousand times and $2 every time it is tapped on."
