Looking for a free Geolocation Service (from Country/Prov/City) or Database?

Question

I am looking for a free service (providing a web service or a database that gets updated regularly) that will allow me to retrieve the Geolocations (Long/Lat) for Country/Prov/City.

Yahoo & Google's API's are unacceptable as they limit the total amount of requests DAILY.

Answer 1

Have a look at TIGER line data

EDIT: In my experience it's not as accurate as NAVTEQ data (i think google and yahoo use them) but its what you get for free.

Answer 2

Have you looked at GeoNames?

Answer 3

I'm a fan of Geolite, they have both city and country databases, freely available api's in a number of languages and they update the databases on a fairly regular basis.
