I have iFunbox.. I can get into everything on my itouch, including what it says when you're unlocking the lockscreen, to changing app pictures.

But there's always a folder iBump into that has a whole bunch of pictures I can edit, but I just don't know where it is.

What's up with that?

Is there a website or a video that shows where these things are?
I don't mind the iPhone things, I know what that looks like... It's just EVERYTHING else I have a problem with.
