I noticed an interesting phenomena last night. While using my HS850 and my 650 I was experiencing the usual less the optimal speaker volume. During my call I received another incoming call. I ignored the call but when the missed called popup appeared, the volume on my call went up about three orders of magnitude. The volume increase was so great I was forced to turn down the volume on my call. If this the true volume potential of the Treo then BT will be just fine.

I wonder what caused the volume spike? Could it be tided to the eventhandler in the Palm OS? Could this be why the mute trick works?
