Hola, iphone-moddingbros.

I have been slowly learning where things like icons are on the phone's file system, and ui sounds and whatnot, and replacing them manually to create my own custom theme. There are a few things, however, that I haven't figured out. One of which is, where the battery icon file is, and can I manually change the system colours/textures. Also is there like a 1-stop thread to info like this?
