So I'm aware you can make themes with winterboard. I know how to have icons for the preinstalled apps (like mail, phone, etc, using the folder com.apple."etc") , However how do I make icons for my theme for installed apps? I'm aware that the apps are located in /var/mobile/containers/bundle/application. Just don't know what to do. The only way I've changed app icons in the past was by overwriting the original file, but I have to redo it all over again if that app needs an update.
