Ok, I recently downloaded Winterboard and have had success installing themes and backgrounds. However, I cannot seem to change the Lock Screen background. It was working, but it has randomly stopped. I deleted LockBackground.jpg in var/mobile/library and that doesn't work. Changing the background through ipod settings doesn't work either. And just to clarify, the LockBackground.png file goes in var/stash/Themes.xxx/User Lock Background.theme/ right?
