Just got my iPhone 5, upgraded from the 4 (not 4s). So everything seems super fast and much better, HOWEVER, I wish I waited and maybe just kept it in the box a while longer till Google gets their version available on iOS.
I really need the color coded traffic freeway lanes. With a quick glance, I was able to pick my route to work. This was the big advantage my iPhone had over the Garmin GPS I have in my car. Now on IOS 6, all lanes are orange and I just have notifications of accidents but I need to know how that affects traffic.
