Pwnage tool does not work for me as it never goes beyond decompressing the ipsw. So I was wondering what the build command for the ipsw on a mac. It is also a ppc so the precimpiled versions do not work. As I am not currently on my computer I am not sure what the file is for ipsw. I would guess it would be something like gcc ipsw. Although it probably needs to have libraries included. so does anyone know what the comand would be?
