I think it's cute how Apple-customers takes for granted that Google will fix Apple's problems to make their life better instead of promoting its own platform.
They could trivially bring Google Maps from iOS5 to iOS6... if Apple wanted them to.
Why do you say that? Google didn't make the the Maps app in previous versions of iOS, Apple did—they just used Google's data.
Apple could, and apparently they have a year left on their contract?
