Hello, At night, since my partner goes to sleep earlier than me, I'd like to mute any sound(push messages, sms, etc.) from my iPhone including "vibration" buzz sound. The only way to achieve is to set my iPhone(3GS, iOS 4.3.1) into Slient mode and turn off the Vibration option. (Though it still vibrates when I start recharging. duh..) It is very tedious to go into options and change every night and revert in the morning so I tried to mute it by simply decreasing the volume to 0 in Sound mode but it just cannot reach 0 for whatever reason! I don't want to complain about this "feature" but would like to know what is the simplest method to set my iPhone completely muted - no sound, no vibration. Even my 6-year-old Sammy dumb phone had "night time" function which automatically becomes completely muted between selected range of hours. Any ideas would be greatly appreciated. Thanks!
