Apple is once again friends with Google, at least as far as mobile ads go.

Google says its wholeheartedly approves of Apple’s relaxation of its mobile advertising policy. The old policy effectively locked out Google’s AdMob platform from in-app advertising on the iPhone and iPad.

Apple’s new terms will open up in-app advertising to competitors and enable advertising systems that work across a range of platforms (IE. iPhone and Android), Google says.

“This is great news for everyone in the mobile community, as we believe that a competitive environment is the best way to drive innovation and growth in mobile advertising. Mobile advertising has already helped to fund tens of thousands of mobile apps across many different platforms and devices, and it will help do the same for many more in the years ahead.”
