SISContents is a tool that allows you to unpack, edit and sign Symbian 9 SIS packages (Nokia S60 3rd, 5th Edition and Sony Ericsson UIQ 3.x platforms are supported). It helps you to inspect the files contained in SIS package, to see certificates against which it was signed as well as to view the PKG script that describes the on-device installation process. You can also edit the contents of packages and sign them after that.
i would like this program's portable.
