Answer 1

No, you cannot programatically set a user's wallpaper in iOS (yet anyway). You can probably do it on JB devices though, but that won't get you on the Apple appstore.

Answer 2

If you are talking about the iPhone background while you are outside of the app this is a repeat question. Otherwise in your own application just set contents of your root views layer to the CGImage you wish.
