first adenali, it depends on if you have the .t9 or the .lng files added. It is possible depending on which ones you added to have either the phone language to be changed (the .lng file) or the writing dictionary (.t9).
second donnygg, yea I must be dyslexic or something, your completely right, its the FS that you need and not the main. and I use main2raw rather than gextract but whatever you use is fine. And don't always expect there to be the .t9 for all the languages. If you really need it, you can always go threw more FS if needed. They are posted here after all.
