Thanks for the reply. Yep, that's the lock i was thinking of but it's a
pain to have to get the stylus out, navigate down the menu system
before getting to the desired app - it would be easier to hold down the
end call ket for 2s to go into this state - like windows mobile 2003se.

Had a thought of trying to use the voice speed dial software that came
installed with the phone but it doesn't list button lock as an app.

I think there's no quick way...shame,
