OpenSocial language problem

[ashcsi ashcsi]

Hello All,

The call to

opensocial.Person.Field.LANGUAGES_SPOKEN

does not return me the correct language. For eg: if we change our language from English(US) to Portuguese(Brasil), ideally
it should return me pt-br, but it returns en-us instead. Should I be using something else?
Please suggest?

thanks
