Can we grab iPhone screen before program launch? Of course it will be grabbed after application launching. But maybe iOS cashes it somewhere so we can access it.

Access to the system-generated stuff is not safe... You can save the state before the app enter the background, then on applicationWillEnterForeground: method worked you can resume the state.
