And what's the deal with the silent setting in the volume control? You set up a custom ringtone for someone but then would want to set it to silent? Makes no sense to me.
The silent setting appears in all of the volume controls. It gives you an option to set some things to silent while keeping some at various other levels of loudness. It is handy when you create a custom sound profile. You might want to set your custom ringtones for certain people for when they call but you might not want to receive an audible tone when that person emails you.
