Google has an iOS 6 Maps app awaiting approval. It is solely up to Apple to approve. | 9to5Mac

Apple may have ultimately done Google a big favor in this context, considering the negative press/blogosphere response to the new iOS 6 Apple maps app; however, note that other channels are asserting that the Google Maps app submission rumor is false

"Separately, we’ve heard Google has been building separate versions of a iOS GoogleMaps.app for quite a while that goes back years. Additionally, we’ve learned an updated iOS 6 version of the Google Maps.app has been submitted to Apple. It is awaiting approval, however, and that could take some time. It took a year for Apple to approve Google Voice, for instance, and Apple could technically likewise claim Google Maps “duplicates a native service” even though there are quite a few mapping apps already in the App Store (like Google Earth). Last month, it looked as if Apple were putting an update to Google Voice that featured Siri-like functionality through purgatory."
