Ok so i previously jail-broke my 3GS MB on limera1n beta 3/4 ( dont remember) and today i restored and tried using greenpois0n for better stability improvements using RC4. It does NOT work for me on 4.1. I follow the steps correctly but it says jailbreak failed I have tried several times. i know it is not user error because i did it on my ipod touch 2g and got it my first try. I have tried Mac and PC, mac didnt work for either devices, but PC worked for ipod but not the 3gs. Is this a bug? What are there differences between RC3 and 4? If its just support for ipod touch 2g then ill try it. I hope someone can give me some insight. Anyone? Phresh restore doesnt work either.
