Blackberry Pearl Dialling Noises

Is there anyway to turn off the noise made whilst keying in the phone number
on a Blackberry Pearl? The T-Mobile IT guy gave up, he was a good one too
having solved various other problems with the phone (the poor store
assistants were far out of their depth in setting up this beast and made a
pig's ear of it). Even setting the profile to Silent does not turn off this
noise.

I've noticed this problem on another phone (LG U300 - I started a different
thread about it to keep any answers focused to the blackberry) re: it being
impossible to make it totally silent. Are the manufacturers being lazy or
are the error-checking procedures no longer fit for purpose in this
category?
