@farraman: Nope, you don't need the old uninstallers, you can use the ones from the latest packages
.
Given the amount of time that passed since you jailbroke your Kindle, I'm gonna assume it's not up to date, so you'll first need to uninstall the jailbreak, then install the latest version.
Once that's done, you can simply install the new version of the ss hack on top of the old one, it'll take care of everything
