So I'm brand new to Jailbreaking iOS, just did it for the first time earlier today on my new iPhone4.. but I am computer literate and picked up the basics quickly. I've done a search but haven't been able to find this answer. Im working with winterboard, Lockinfo, and various other things to make life easier. I found a theme I like that is simple... just includes some changes to the lock/unlock bar and the theme included a home screen wallpaper.png image that I didn't like, and deleted in iFile. This initially did come up and apply itself to the homescreen background However in /var/stash/Themes it does have a LockBackground.png wallpaper that I do like and would like to keep as default on this theme. But I cannot get it to automatically change to this particular background for the lock screen when I switch from this theme to another and back again. I've read that I should have this theme on the top of the list in winterboard to keep others from overriding it, which I do. I just want to be able to switch easy between themes and have the lock screen background change with the theme upon doing so.. and not have to switch it manually under the native wallpaper menu in settings. There has to be something very simple I'm missing, what is it?
