So I just got an iPad 2 and it had 5.01! So I went and jail broke the pad and then ran to backup my shsh blob file (wrong terminology?) and read up that 5.01 shsh files are useless since I missed the "window". I used tiny umbrella to get my file just to be on the safe side. What's my next move? What if I want to go back to un broken 5.01? What about general backups for that "oh ****" situation? I think my next move is waiting for the 5.1 "window" did I miss it already? It's been a long time since I've danced with apple on the jb scene so any help for an old timer would be great. Thanks guys!
