What is an SHSH blob?
An SHSH is a secure signature hash. It’s used to verify the iOS version you’re running. Without these signatures you might not be able to downgrade to an older firmware. Basically its a unique key for each device. To avoid a lengthy discussion, you need to Save SHSH blobs.
What is iFaith?
You can save SHSH blobs for the latest firmware only, because Apple stop signing older firmware as soon as a newer one is out. Tools like TinyUmbrella and Cydia are already good at saving latest firmware SHSH blobs. iFaith, however, is the first application that can save SHSH blobs of an older firmware/iOS *currently installed on your idevice* and creates a pre-signed IPSW.
Programs like TinyUmbrella and Cydia are able to store SHSH blobs but are limited in capabilities. These programs do not allow physical retrieval of SHSH blobs and they only can retrieve SHSH blobs that are currently signed by Apple. For this reason, the SHSH blobs are on a time constraint.
iFaith is available for the Windows. Mac version is still ind development. Latest version is always available here. You can download iFaith from here:
