For those who don’t know, TinyUmbrella lets you save SHSH blobs for iPhone, iPad, iPod Touch and Apple TV which are required to be able to downgrade device firmware to an older version. Some of the recent untethered jailbreak tools like Redsn0w 0.9.7 also uses SHSH blobs to provide untethered jailbreak.
Though I have been busy, I have not forgotten you. I’ve just added iOS 4.3b2 support. For those of you with Apple Developer accounts, this means you can save your SHSH’s for that version and restore to it permanently. Keep me posted of any issues. I’m still working on my next big contribution to the scene… 🙂
EDIT: Ok so I had a FEW bugs. 4.21.05 should work peachy 🙂
