It seems to me I read someplace there was a setting on
the 6010 for phone sound quality. I can't seem to find
the info now though. All I can recall is there's supposed
to be a default setting of average sound quality through
the earpiece, but an enhanced setting was available
but it would run your battery down quicker. I don't
mean audio volume but quality(maybe a higher bitrate
used?) This is in the earpiece that's part of the phone,
not any headset etc..

I thought it was adjustable without using
a data cable, but my memory may be faulty.

Anyone know of such an adjustment?
