iOS 6 Maps Problem
I am on the iOS 6 GM and have noticed a big problem that people are really going to struggle with. In applications, when you select "Get Directions", most apps take you out of the app and into google maps in safari. From there, you are completely stuck. You have to either copy and paste the coordinates into the maps app, or remember the address and then go type it in Maps. It is a HORRIBLE user experience.
I noticed that Yelp takes you into the maps app correctly, but most apps do not. Even TripIt, which was supposedly updated for iOS 6.
