This article seems off. I think you are confusing the mapping data (i.e., the maps with the street names, etc.) with the location data (i.e., position without GPS, using WiFi and cell tower triangulation). The latter is what SkyHook does. I think Apple is still using Google maps for its mapping DB, but is no longer using SkyHook for its non-GPS positioning system.
