[regression]

I would like to set my Touch Pro's volume (by pressing the volume keys on the left or they speaker icon on the top) for System = Silent, Ringer = sound. Does anyone know if this can be done? When I go to the volume screen and click Silent on the System tab, the Ringer tab is also set to Silent. When I change Ringer, it also changes System. I would like for these settings to be independent of each other. Is that possible?

Thanks.
