ok i got my new n900 today (on my 3rd n900 now) but it was bought from china, im in uk. all was well then i spotted some chinese keyboard apps in app manager so i deleted them. now my fn and shift lock dont work and long press doesnt either

any wizards that know the solution? really dont want to flash.

another question, if i install cssu will this essentially flash my n900 so that these keys will work?
