I ain't sure. I would love it to be real, but there's one or two things that lead me to think it might not have come from/approved by Apple's software engineers. The main one being the buttoons "under" the googlemap. I like the look of this, but it's not consistant with any other application, why, for example, does it not flip over like the Weather app?
Also, now googlemaps on-line has done away with the "hybrid" view option, (instead putting the mapping data on satellite view by default) why would they retain the hybrid and satellite views on iPhone?
