Programmatically powering off an iPhone?

Question

Is it possible to programmatically power off an iPhone or does Apple disallow this?

If Apple disallows this, is it possible to programmatically mute the sound on an iPhone?

Answer 1

The iPhone applications you create with the official SDK are sandboxes in and of themselves. Walled off sandboxes with barbed wire.

You won't be able to turn off the power. And muting sounds other than your own applications' sounds amounts to being able to turn off the iPod playback.

Answer 2

I don't have any evidence for that, but this would involve modifying the "UserExperience" - which is something that Apple never would allow (and why still many people jailbreak their phones).

And this involves "power off" as well as "mute sound" - because both could destroy the UX (you wait for an important call, but application X broke the sound).
