Graham Spencer from Macstories has a great post describing the history of services in iOS. The graphics are plain and simple. There is a clear direction in which Apple is integrating with more outside services. Google is almost out.
Most of the recent iOS discussion is how good will Apple maps be? Could Apple replace the mapping application which had become our de facto standard?
But even if there had not been bad blood with Google I wonder if this would have happened anyway. If you follow the timeline Apple really had a lot in one basket with Google.
