Hi Duncan
Today I've received my brand new fbus cable. I've tried it with an old 
3310 and your software works perfectly. I think I will test it a lot 
because nokia 3310s are very common here in italy. I will keep you 
update with my impressions and so on.
Other than the links in your code, is there some official documentation 
about the fbus protocol?
