I'd like to be able to set the lockscreen background image programmatically. I'm aware that this is only possible for jailbroken iOS devices. Here are some things that I've tried: Place a LockBackground.png in /private/var/mobile/Library/SpringBoard/. This works but requires a hard respring. notify_post("com.apple.language.changed"); doesn't work for a soft respring. Use class-dump to dump private methods of UIKit. UIKit in 4.2 used to have a method called + (void)setDesktopImageData:(id)fp8; but it appears to be missing in 4.3 and above. Is there anything that I'm missing?

Setting iOS background/lockscreen image programmatically?
