In this Guide you’ll learn how to save SHSH blobs for iPhone 3G and iPod Touch 2G. Now, it’s necessary for iPhone 3G and iPod Touch 2G users to save SHSH blobs to secure future jailbreak just like we do for iPhone 4, 3GS, iPod Touch 3G, 2G (MC) and iPad.
Why to Save SHSH Blobs for iPhone 3G and iPod Touch 2G?
Dev-team explains: Those of you with jailbroken iPhone3G and ipt2G devices may now have noticed Cydia starting to save your SHSH blobs too, just like it does for iPhone3GS, ipt3G and later devices. That’s because starting with 4.0, Apple started putting a “soft” SHSH blob check in the firmware. The SHSH blob check is very real in the sense that if iTunes can’t get your blobs (because the Apple signing window has closed), the iTunes restore will error out. But it’s “soft” in the sense that those devices can always use redsn0w or PwnageTool to get past the error (the bootroms themselves for those devices don’t require blobs to be in the firmware files, unlike the newer bootroms).
Furthermore, since the 3.x IPSWs for these devices don’t enforce it, you can always restore to 3.x IPSWs outside of any signing windows.
So, Cydia is doing this to allow you to continue to use iTunes to restore to 4.x on iPhone3G and ipt2g outside of Apple’s signing window without needing to use redsn0w or PwnageTool to get around Apple’s annoying new restriction.
- iOS 3.x firmwares for iPhone 3G and iPod Touch 2G are NOT affected by Soft SHSH signatures, so you can restore OS 3.1.3, 3.1.2 or older without SHSH. This applies to OS 4.x only.
- It’s too late to save blobs for iOS 4.0 firmware but NOT for iOS 4.0.1.

On iPod Touch 2G FW 3.1.2 MC Model I saved via Cydia 3.1.2 SHSH blob.But for some reason a message saying:“This device has a SHSHs on file for iPhone OS:4.0″ appears on the top of Cydia Home Page….I am confused:(
I have a iPod Touch 2G iOS4.0 and says the same thing. At one point in time I did a jailbreak but reverted back to the stock FW, so I don’t know if it’s just keeping it or what.
how did u revert it back to the old FW? I am already on iOS 4.0 and no luck for me using TinyUmbrella:(
My iPhone3G has SHSH saved on Cydia. Could you tell me how to get it when I wanna use it or save it to me pc?
TinyUmbrella does not support iPhone3G. There is no iPhone3G to choose in Device/Version from Advanced Options.
Yes it Does.. make sure it’s version 04.01.03

i have an iphone 3g that is upgraded to 4.1 but it has never been jailbroken. can i downgrade so that i can jailbreak my phone?
Yes, you can downgrade iPhone 3G to 3.1.3 or older firmware
but in order to downgrade it to iOS 4.0 / 4.0.1 or 4.0.2 you must have SHSH saved
Ok, so iPhone 3G and iPod Touch 2G users can save iOS4.0.1 SHSH blobs with TinyUmbrella, what about 4.0.2 and 4.1? Those blobs will be useful if said users ever reinstall the iOS whose blobs they have (4.0.1+) for them to jailbreak, correct? As NotCom is currently updating TinyUmbrella, should said users wait for the update before trying to save the blobs? Also, said users can downgrade from 4.X to 3.X without needing 3.X SHSH blobs?
