Hi, is there a way to set the ringer volume to 0 without using the "mute" button ? When I'm at work I do not want the iPhone to do any noise and I do not want it to vibrate either. I know I could disable the vibrate when "on silent" but I need the vibration when I'm not at work. Going everytime to the Preferences and switching takes to long. When will Apple add some ringer profiles in iOS ?? We are in 2012 now, come on Apple, you can do it.
