The appeal of the iPhone is global – iPhone users live in many different countries and speak many different languages. You can ensure that your application is ready for this global audience through the processes of internationalization and localization. Internationalization is making sure your native cultural information is not hard-coded into your application. (By cultural information, we mean language, currency, date formats, number formats, and more.) Localization, on the other hand, is providing the appropriate data in your application based on the user’s Language and Region Format settings. You can find these settings in the Settings application by selecting the General row and then the International row.
