The Bumpy Road on iOS 6 Maps
With the release of iOS 6, Google's fantastic mapping data is no longer available in a native application. Apple has taken the bold move of creating their own mapping solution. It's in an infant stage of development and will get better with time as user data is assimilated.
I thinks it's safe to say this story will be very popular in the press and in real life it will frustrate users. But the sky isn't falling. This isn't a death blow to Apple. It seems very likely that Google will submit an iOS native mapping application to the App Store. There's no way Apple doesn't approve it.
In the interim, if Apple's map application isn't getting the job done for you, there's a temporary solution available. Head to www.maps.google.com on your iOS device and then bookmark the link to your home screen.
