However, earlier in the week – iH8sn0w – developer of jailbreak tool Sn0wbreeze released an updated version of iFaith to add support for dumping iOS 5 SHSH blobs, which unlike TinyUmbrella allow users to downgrade to an older version of iOS if they had dumped SHSH blobs with the apticket using iFaith.
It looks like it is going to be soon possible to downgrade using SHSH blobs saved using TinyUmbrella, according to a series of tweets by MuscleNerd of the iPhone Dev team.
Upcoming redsn0w release makes both TinyUmbrella and Cydia blob saves useful for 5.0+ (1st verifies, then stitches)
For time being, please just use most recent TU to save 5.0.1 blobs+APTicket…redsn0w will do the rest, should you need to restore.
MuscleNerd hasn’t provided any details of how it will work nor has he provided an ETA on when the new version of Redsn0w will be released, but as he has recommended it is a good idea to take SHSH blobs using TinyUmbrella, which is available for both Mac and Windows or iFaith.
