I have an iPhone 4s and recently updated it to iOS 6. I tried the new operating system and fund it much better than the previous one. One feature that I have still not tried is the Maps that are available in it. Actually I watched its demo and saw that the maps will be presented in a 3D format. All the buildings will be shown in 3D format and all the roads. It will also inform us about the traffic, alternate routes, any problem on the route and many other details. I wanted to know these maps will work on GPS or on internet connection in the phone. If it will be using the internet, then I think that a lot of data will be consumed. What do you people think about it?
