I have an iPhone 5. I never had problems with the map app, not that I used it much. But where I did use it was while walking around in downtown San Francisco. I loved the 3D views I could get. I could rotate around buildings and look at all sides. It was great. I had been there 3 times and was using the 3D maps to great advantage. Then today I went and 3D wasn't working. Sure I could tilt the surface, but I was tilting a 2D view. I could not rotate around a building and see all sides. It seems like they have taken something away that (at least in San Francisco) was working well. Note that the 3D that did work only worked in major cities. It didn't work in my home town of Benicia (30 miles from San Francisco). Anyway, I think in their attempt to "fix" the problems with maps, they've removed the 3D feature. I hope that's just temporary and that they'll get it back at some point.
