While Google remains the primary search engine on the iPhone, they couldn’t have been pleased with the latest release of the developer version of iOS4. It seems the new developer agreement has been modified to disallow third parties, including Google’s newly acquired AdMob subsidiary, to share ad analytic information with its customers who have placed ads in applications on the iPhone.

“The collection, use or disclosure is for the purpose of serving advertising to Your Application; is provided to an independent advertising service provider whose primary business is serving mobile ads (for example, an advertising service provider owned by or affiliated with a developer or distributor of mobile devices, mobile operating systems or development environments other than Apple would not qualify as independent); and the disclosure is limited to UDID, user location data, and other data specifically designated by Apple as available for advertising purposes,” reads Section 3.3.9 of the agreement.

Apple recently engaged in a bidding war with Google over AdMob, which eventually sold for $750 million. Apple instead is launching their own solution called iAd.
