TinyUmbrella now supports 4.3.3 and 4.2.8 (Verizon). Sorry for the delay, I’ve been quite busy. I’m working on some pretty drastic changes for TinyUmbrella.
For those unfamiliar, TinyUmbrella lets you save SHSH blobs for iPhone, iPad, iPod Touch and Apple TV right from Apple Server and also from Cydia. SHSH blobs are required to downgrade device firmware to an older version. Some of the untethered jailbreak tools like Redsn0w 0.9.7 also uses SHSH blobs to provide untethered jailbreak solution.
