For the iOS 6 betas, the main city I am in (New Orleans) had the 3D support, but not the suburbs I live in. In the last 2 weeks it appears that the 3D feature has expanded in to my area, and way past it! It seems that the entire city (all those subcities) that associate themselves as New Orleans have 3D support. I know it's insignificant in the big scheme of things, but I'm excited. What about you? Where are you and is your home/city supported by 3D view yet?
