I just tried jailbreaking my 3GS using the latest Greenpois0n version. I followed the instructions to put it in DFU, and began the jailbreak. Everything went smoothly, the white screen appeared just like it should, and then it switched to jailbreak failed. The white screen stayed up for around 5 minutes, the phone rebooted and went back to normal. It's not jailbroken. Should I just try the jailbreak again? Do I need to restore before I try again even though the phone seems like its in a perfect non-jailbroken state? Any help would be GREATLY appreciated, Thanks in advance.
