I realy can't wait any longer for an untethered jb for my iOS5 iPhone 4. So if I redsnow it and use a tethered jb, when the untethered finaly is released will I have to re jailbreak and loose all my cydia apps and tweaks. Or can I just jb over the top of the tethered redsnow meaning I don't need to install everything again? Cheers guys
