How do you change unlock screen background?

[docc]

Hi,

I've managed to pretty much do every bit of hacking there is on the iPhone but i cannot for the life of me figure out how to change the background image in the unlock screen.

I've changed the wallpaper of the home screen but my unlock screen image just does not seem to be configurable. Can someone point me in the right direction?

Thanks.

Whatever is set as wallpaper is also used for the unlock screen - unless you are plugged in, in which case its just black.
