Yes, I believe so.  As others have said, "honesty" includes not only
the past but what is planned for the future.  I think changing the
gauge immediately (40%, 60%, 80%) but having it be grayed-out would be
a good way to represent that the volume change is queued up for later

Plan A would be acceptable, but B would be better.  The user interface
should waste as little of the user's time as possible.  However, plan
B also sounds like it'd be tricky to do correctly.  What happens if
the user immediately tries to make another call (or use GPRS or SMS)
and the previous call hasn't yet finished?

Thanks for your detailed response, Mirko.  I look forward to testing
your next release.
