I see the same behavior on my iPhone 4. When I zoom in so the screen is about 5 miles square, it becomes all blue. Zooming out restores maps on the side, but not in the old zoomed in region. If you slide the blue region off the screen (at the same magnification), the maps appear when you slide it back on. Behavior is the same if you select WiFi or Dataplan in the settings.

If I zoom out the map is there but when I zoom in the flight area us just a blue background. If I scroll over a few miles outside of the flight area the map is appearing. It is as if it is being over written.
