    If your 3GS was previously jailbroken (old bootrom, at 3.1.2, not new bootrom, and not on 3.1.3 w/ Spirit), then you should in fact be able to downgrade.

    Only if you were previously jailbroken on 3.1.2 using BlackRa1n. What iOS are you running and when did you JB?

    Originally when my SHSH files were backed up on Cydia, I had 3.1.2 jb with blackra1n. At some point, I was tricked into upgrading to 3.1.3 and had to jb my phone all over again using Spirit. Is it still possible to use my SHSH files to downgrade back to 3.1.2?

    CRAP! I spoke too soon. Email still crashes when I reply to some messages.
    The good news, though, is that now I know I can go ahead and let iTunes upgrade me to 4.0.1 official and see if it still happens there (or if this is somehow jailbreak related.)

    For some reason Cydia tells me I don't have SHSH's stored. Now when I initially JB'd my 3.1.3 3GS only 2 days ago I definitely chose the "Make my life simpler" option and definitely saw the main page saying that I had my SHSH's saved. Any reason why they're no longer there? Surely they wouldn't have been erased after I stupidly tried to upgrade to 4.0 and failed.

    Appologize if my questions are silly, but will this work if I don't have my SHSH backed up to Cydia? I just purchased online an Iphone 3GS with OS 4.0 loaded. I backed up SHSH now, but I don't know if the previous owner did it. If I will try to downgrade and SHSH is not there will it screw up my phone? Also, How do you find out what BOOTROM version is new and which is old and what version I have? Thank you in advance. Forums here are the best. Quick and knowledgable group of people in here. I am glad I found this place and I am doing a lot of reading.

    you are out of luck if you dont have your shsh blobs saved. Without the previous 3.1.2 shsh you cant downgrade meaning you wont b able to jailbreak.. for now.
    You can check what bootrom you have by downloading f0recast from www.ih8sn0w.com
    Keep checking the forums daily for the jailbreak o ios 4.0 or 4.0.1 which should be really soon. Also make sure to follow Planetbeing on twitter for his progress on the jailbreak.

    I have a iphone 3gs with old dorm. It automatically upgraded to 4.0 by accident. I have 3.1.2 shsh saved on Cydia. So I changed host file to point to Cydia, put iphone to DFU mode and try to restore 3.1.2, but iTune displayed firmware error message, and didn't even try to restore the 3.1.2 firmware. I have followed the instruction step by step and wonder what I missed. Why others can use this method to restore old firmware, but not my 3gs. Any help will be appreciated.

    From what I learned so far, and I want to point out that I am far from great knowledgable guys in here, I think your 3.12 firmware is not matching. It has to match exactly, to the number (those several numbers after 3.12) in order for you to be able and roll back. I had this issue and until I matched the exact version of 3.12 it was giving me errors.

    I was told that a new jailbreak and unlock is in the works and should be out very, very soon. Is that the case?

    Hello, I have a brand new just opened IPOD Touch 2G with an old firmware 2.1.1 and have not JB nor upgraded to 4.0 which Itunes wants me to do. The problem I am having is trying to upgrade to 3.1.2 from 2.1.1 using the technique written here about editing the /etc/hosts file to point to Saurik's Cydia server address gs.apple.com

    I have put my IPOD Touch 2G into the DFU mode as instructed and downloaded the 3.1.2 firmware from the german site which points to a megaupload site. The file starts to extract but when it tries to talk to the apple server (which really is Saurik's Cydia server) it fails after a while with error code 3194 which is the same error code before I pointed gs.apple.com to

    This unit has never been modified/JB/upgraded to any newer firmware. As such it has not had its SHSH blogs saved to Cydia because it doesnt even have Cydia installed yet because its got a fresh old 2.1.1 firmware.

    Can anyone help with what needs to be done to successfully upgrade to 3.1.2? Or am I unable to do because the SHSH blog keys were never saved to Saurik's Cydia server database?

    I see you mention that I need blobs? Could you please send me a description of what I need as far as blobs goes and how to install and where to find it? I have windows 7 starter and I put the apple redirect info in the hosts file. It wouldn't let me save it but I saved it to documents then dragged it over to the etc. Folder and erased the old one. But could you please tell me what blobs is and where to find it? You can send it to my email [email protected]

    And also could someone please give me a detailed description (for computer illiterate folks). On how to downgrade from 4.0 firmware to 3.1.3 firmware on a 3GS phone with windows 7 starter software? Everything I need and need to do? Pleeeeeeeeaaaaaasse

    I am on 3.1.2 and the device got frozen. I have restored the device by mistake to 3.1.3 and then reverted back to 3.1.2. The base band is 5.12.01 and boot loader is 6.4.Model MC137.

    Any chance/Way for me to JB and unlock the phone to either 3.1.2 or 4.0
