Why don't you just put a silent toggle switch on one of your homescreens.
Some of you are making too big a deal of this.
What exactly are we talking about here? Are people complaining about turning off the ringer? If so, there is already a row of toggles in the notification bar. Or holding the power button down. Or if the ringer goes off, and you want to mute it, just turn the phone over. So many options and all easy. Don't understand how anyone can complain about this.
