There isn't so called language packs like some other phones have. You have the .lng (the phone language) and the .t9 (the T9 dictionary) files. You can use main2raw and SEFStool4 to extract the .t9 and .lng files from FS that contain the languages you want. You can see what files each FS contains here. I wrote a tutorial a while back to walk you through the instalation of the files. The tut can be foundhere
