Ti.Locale not working after changing simulator language (I HOPE this works on physical device!)

Hi, I set the iPhone simulator language to spanish and italian (I eventually verified the change), but, when I test my app, the following code always detects english/american language:

Ti.API.error("locale: " + Ti.Locale.currentLocale);
Ti.API.error("country: " + Ti.Locale.currentCountry);
Ti.API.error("language: " + Ti.Locale.currentLanguage);
Ti.API.error("locale: " + Ti.Locale.getCurrentLocale());
Ti.API.error("country: " + Ti.Locale.getCurrentCountry());
Ti.API.error("language: " + Ti.Locale.getCurrentLanguage());

[ERROR] :  locale: en-US
[ERROR] :  country: US
[ERROR] :  language: en
[ERROR] :  locale: en-US
[ERROR] :  country: US
[ERROR] :  language: en

My project is multilanguage and in multiple places I use L("string") localization system. Anyway, if this simple example doesn't work, I don't know how could work the rest of my project.

Other infos here:

Any help is appreciated.
