First, you will have to be rooted. Install Root explorer or the like. Then go into the root and start searching. It is probably a PNG inside a zip file. There may be a whole collection inside the file with a reference file that points to it. It could also be in a resource file (ext. RC) Many development enviroments have resource editors.

I would grep on *.zip and poke around and if you do not find anything, try *.RC.

Good luck on your quest. Let us know when you find steady work.
