Pretty much as the title says. I heard that Spirit does not work with it and I'm wondering if there's any jailbreaking software that is compatible with the latest iTunes version (which the numberical version I'm not aware of). I've tried uninstalling the latest version and installing 9.0, but it looks like they've put on a way to stop that. Even though I went and uninstalled it, it looks like it kept part of the latest version and says that it can't install the old version because of it. So are there any programs that I can use with the latest version of iTunes? If it helps, my OS is a 64-bit Windows XP.
