Retrieve country name from iPhone gps without internet!

Programmer Question

Hello,

In my application on the iPhone and iPod Touch I want to be able to retrieve the country a person is in without accessing the internet. I know how to do this with internet, so I know how to retrieve the longitudes and latitudes, I've read something about a file with the world borders included, but I don't know how to use this in objective-c on the iPhone.

Does anybody know a fairly easy solution to retrieve the country name from the iPhone's GPS-coordinates without using internet?

Thanks in advance,

Fabian
