The top iPhone International Setting Option is to change the Language. The default for American iPhone users is going to be English, but when you select this you will see a few dozen other languages and dialects that you can put on your iPhone. Once you select the language of your choosing the iPhone will reconfigure to that language, which is a process that often takes a few moments. Once it has applied the setting, everything in the iPhone, as well as iTunes and the App Store, will be in the selected language.
