Schmidt said Google and Apple were in constant communication “at all kinds of levels.” But he said any decision on whether Google Maps would be accepted as an application in the Apple App Store would have to be made by Apple. “We have not done anything yet,” he said.

Last week rumors surfaced that Google had readied a new Maps app for iOS 6, and that Apple was dragging its heels to approve it. This confirms that the rumor was wrong.
