There's no doubt that iPhone 3G is going to [or has already] stimulate mobile map usage in North America. Interesting that I found this recent quote... "It surely won`t be long before Apple`s iPhone line up is the leading device for mobile maps usage. Just you wait and see." An aggressive projection, however, keep in mind that the World is a big place and there's many mobile users outside of North America... most of then not using iPhone. To say that iPhone will soon pass Nokia in this space is shortsighted to say the least. iPhone to dominate in this place soon... don't be foolish!
