iPhone New York Subway Map Case

Here is a great idea: An iPhone 5 New York Subway map case that shows you where the subway stations and such are all on the back of your iPhone. A very clever and cool idea.

Overall this item is a great idea and not a bad price for it really, either. A pity more cities around the world are not included and some might question this type of item when you could just have a native map app of some kind on the iPhone itself. Still, good idea.
