I have a registration form i made where users can select their Country, State and the city they live in, but I cannot find a list of all the Countries, States, and Cities from around the world.

Does anyone know where i can get a complete full free list from?

Google queries like this "Cities of the United States", "Cities of Nebraska", "Cities of India", "All the countries in the world".

Just replace what needs to be replaced. The countries one is easier if you use the CIA Factbook that's available online:

https://www.cia.gov/library/publications/the-world-factbook/

Here's some breakers for you:

India's cities: http://en.wikipedia.org/wiki/List_of_cities_in_India

City's and towns of England: http://en.wikipedia.org/wiki/List_of_towns_and_cities_in_England_by_population

List of states and their cities: http://en.wikipedia.org/wiki/List_of_cities,_towns,_and_villages_in_the_United_States

You want a list of all the cities of all the countries in the world?? That would be a little excessive. Even a list of all the cities in particular states in the US would be excessive.

Why not just make the City box a text field?

Good idea about making the city state box field. I created that list, and trust it's not an easy beast to get a hold of. IT WILL default Afghanistan to the top of the list at all times. Not to mention no one actually likes scrolling through those lists. Do you?
*edit* you can modify it to make a default selection but still when the user clicks the box they will have to scroll through to pick their country if it not the default.
