    Not quite true.
    If you buy a phone with a jailbreakable FW you can get the signature files (the already encrypted blobs) for that FW so can always restore that.
    For example, if iOS 4.4 was released and there was no JB but you bought a brand new phone with 4.33 on it and Apple had stopped signing it, without this tool you would be able to JB your device but if you ever had to restore you would be forced to upgrade to 4.4 as umbrella could only get the blobs for FW that Apple are still signing.
    IFaith will let you get the signed blobs off your device for 4.33 so you can restore to that.
    If you bought a second hand phone with 4.21 on it which had never had blobs saved then iFaith will get the signed 4.21 blobs so you can restore to that, in this case you would not be able to restore to any FW between 4.21 and 4.4 as those blobs were never retrieved.
    At least, that is what I believe, I'm sure I will be corrected if I'm wrong.
    This will be a very useful tool for some people congratulations to iH8Sn0w for a great job.

    Listen Peanut Brain. That's what I said. No phone is unjailbreakable because if you get one on a lower FW you have blobs. (and current fw you already have blobs)

    So if i buy an iphone thats your able to JB then you do and you save the shsh, then when you have to restore it you just download the 4.x.x that you had and click on shift restore so you can pick that old FW, so it really doesnt matter in that way. What i want to know like One1 mentioned above is that if i buy an unjailbreakable device, then will i be able to dump the SHSH and use older firmware that is jailbreakable? and by the way i know i could find the answer online but what is the latest firmware you can JB WITHOUT having any SHSH files saved?

    Thanks in advanced

    Give it time. It will appear to loop over and over and over. Mine took over an hour to complete.

    Just an FYI if you try to build a signed IPSW after dumping the SHSH blobs using this program, you will need to rename your blob file. You must add the ".ifaith" extension in order for the program to see the blob file on your machine.

    Please excuse my lack of intelligence.
    Any phone can be upgraded to the latest FW and JB at the moment so are you saying this is unnecessary? Or am I missing something?

    If you have previusly saved the SHSH blobs yo can upgrade to 4.3.3, but if your phone CAME with 4.3.3 then there is now way to downgrade to 4.2.1 or jailbreak the current 4.3.3 the phone came with.
    Is there any way i can JB a brand new 4.3.3 iphone 4? according to what ive read you dont upgrade your baseband but the phone has the newest baseband available. I need to wait for the 4.3.3 JB right since redsnow is only for previously iphones with old shsh blobs saved?
    Again thanks in advanced.
