Is there a way to change the volume of the device? I've seen several apps do it. 

I have a desktop version of the iOS app and the device will be able to be controlled to some extent over the network. One of the things I want to allow the user to do is change the device volume and then play a sound. This can help if you loose your iPhone in a crack in your couch again, but can't find it. 

Is there any way that you can do this without Apple getting angry?
