I just jail broke about 3 weeks ago before 4.3.4 came out. I was told Cydia saves your SHSH automatically so I never worried about it. Once 4.3.4 come out I wanted to make 100% sure so I downloaded iSH**** and saved my SHSH and sent a copy to my email. Did I save it in time? Or did I need to do it before 4.3.4 come out? I havnt synched since I jail broke.
Second part of that question is why do I see 4.3.3 4.3.4 up top when I open Cydia? Not sure how to post a screen shot from my iPad 2.
