I just acquired an old communicator 9210 with english keyboard layout. However I'd like to have finnish layout on it, because I use scandinavians quite a lot and its painful to keep picking them from character list.

If anyone can instruct me how to do this, I'd be grateful. I already tried looking from manual and net, seems to be something impossible to find

I hope that I don't have to flash it.. For examble, is there any add-on programs available that does the job?
