Use phone number for location info in the absence of an address

[Phil Haack]

I don't have an address for all my contacts. But many of them have phone numbers. In many cases, I can rely on the country code to at least know which country someone lives in. For US people, the area code tells me a lot. Of course, in many cases the area code won't match where they live since people often keep their numbers when they move, but it's good enough.
