Maps© — Social Networking — Free
If you want to use Google’s Street View function without having to go into Apple’s occasionally dodgy Maps, you might want to check out Maps©. In addition to letting you look at people’s lawns like you’re there, you can also drop pins between two points to calculate distance (this gets less accurate the farther apart your points are), check traffic, and get directions. And if you want to see where your friends live (which is creepy, but I’m sure you might have innocent reasons), you can import their addresses from your contacts and drop pins there.
It does a bit of everything, really..
