    I have a 3gs iphone JB and unlocked for 3.1.2, Unfortunately i was not able to save SHSH file, I did install INFINIDOCK from Cydia and the phone rebooted, i ran blackra1n several times but it cannot JB, when I ran blackra1n it shows on the screen for a while and the phone get off itself. I have tried igoogle recovery aslo but failed, Any solution please

    Did you try Redsn0w? It works well, but if Blackra1n isn't working then it may not work either. It should work though. Download redsn0w 0.92 and the 3.1.2 3gs firmware from this site or another googled site. Launch redsn0w and you follow the onscreen instructions. If you installed something from Cydia or have Cydia, then you are already JB. Sounds like you are in the Blackra1n boot cycle that a lot of people are having. Check this site as others have left their phone plugged in and continuosly rebooting for hours to come back to a JB working phone.

    No, redsn0w 0.9.2 is what should be used for a 3GS on 3.1.2 - 0.9.4 was actually specifically made for the ipt2g old bootrom.
