The past few days said ca iH8sn0w is working on a small program with the help of which you will be able to jailbreak with Spirit plague blackra1n without having any problem with blocking the phone after the reboot. Unfortunately iH8sn0w announced last evening that he abandoned work on this project so that all those who need untethered jailbreak they will have to either switch to 3.1.3 firmware with a custom ipsw or to stay where they are if they don't have one SHSH-s saved in Cydia.
I'm sorry, but this is the news, before you start restoring with a custom ipsw I warn you that there is a very high possibility that the process will not work and you will have to restore to 3.1.3 firmware and you will lose decoding, so be careful.
