Mute/Silence an iOS device programmatically?
Is it possible to turn off the silent mode of an iPhone programmatically? I need the option to turn on and mostly off the silent mode, without using the hardware.

Global system volume, including your application's volume, is handled by iPhone OS and is not accessible by applications.
If it were possible, the device would en up in an inconsistent state: the hardware silent-mode button turned on, but in software silent mode is turned off. In short, user experience hell.
