Apple Maps hasn't had the best start and it could soon be under attack further if Google Maps is approved for iOS 6 after it was removed by Apple along with YouTube
Google Maps for iOS 6 is nearing the approval stage according to sources close to the matter. Google has apparently already been giving beta copies out to persons outside of the company.
It would seem however as though Google are indeed nearly ready to file their replacement to Apple for approval which would then mean waiting to see if Apple would indeed approve such a direct competitor to their own maps service.
Apple Maps was launched along with iOS 6 and quickly came under attack from users thanks to inaccuracies with the data, it's believed that this is the reason Scott Forstall was told to leave the company as he was in charge of Apple's own mapping service.
