4. Download the [APP] Scandinavian KB Tool
Install and run this program. when its upp Select Norwegian. NOT swedish. Restart the Phone and you will be able to type åäö using your hardware keyboard.
5. now open the registry editor and go to [HKEY_CURRENT_USER\MUI]
and put in on "CurLang"=41D
this will make whole meny swedish
6. now to make your t9 swedish WITHOUT crewing upp your Hardware keyboard.
