The maps app is the big thing for iOS 6. Though it looks like total garbage compared to Google Maps. Which is total garbage compared to the Android version.
I don't know about that. I prefer to use my iPad for Maps as my CyanogenMod 7.2 Android phone constant has GPS locking issues and sometimes refuses to load, or crashes. I've never had Maps on iOS crash on me. Ever. I do prefer the Android version when it works due to Turn by Turn Navigation, but I have to flip a coin on whether it's going to work or not.
