Just got a brand new ipad yesterday. Without thinking, I let iTunes install the update to it before checking about what I needed to JB it. So then after I got my new shiny 4.2.1 on there, I find out that there IS a JB available, but it is a tethered one. But then I read that there should be a new one available before xmas that does not require tethering, however it requires the SHSH blobs from an older OS version. Unfortunately, I did not know this before I updated and did not save my SHSH blobs. Am I screwed out of any hope of ever JBing my 4.2.1 ipad? What steps should I take to get it to a place where I can use a non-tethered JB? I've read about installing older IPSW files and found directories of them, but I'm not sure if its as simple as installing that and then using something to save the SHSH blobs that result from that. Please tell me I'm not eternally screwd!
