I think something went slightly wrong when I tried it. Something about fetching failed, I'm not sure exactly what it was.
I saved my SHSH blobs before jailbreaking, now I'm going to restore through iTunes and try again. Since it was on 4.3.3 before though, and now it's still on 4.3.3, do I have to restore the SHSH blobs or can I just restore without bothering?
