Answer 1

Starting with iOS 5 you can set UIScreen's brightness:

This property is only supported on the main screen. The value of this property should be a number between 0.0 and 1.0, inclusive.

Brightness changes made by an app remain in effect only while the app is active. The system restores the user-supplied brightness setting at appropriate times when your app is not in the foreground. So if you change the value of this property, you do not need to record the previous value and restore it when your app moves to the background.
