Is it still being prohibited changing lock screen(wallpaper) in iPhone OS 3.x?

Question

I checked this posting, so it was impossible to do it. But it\'s old posting, and somebody are saying me there is an app which can change wallpaper(lock screen). Is this allowed

Answer 1

As far as I'm aware, you would not be able to change the wallpaper for the device through the SDK, or at least not in a way in which Apple would approve of. I suspect allowing this through the SDK could cause problems, apps could obnoxiously add advertisements to the wallpaper, etc.

The only way I can think of around your problem would be to save the target image to the user's camera roll and instruct the user to change it for themselves.

There may be a way to change the wallpaper for a jailbroken device, but this of course violates the iPhone developer program license agreement.
