TinyUmbrella has been updated to version 4.33.00 which will save SHSH blobs of iOS 4.3.3 for iPhone, iPod touch and iPad and of iOS 4.2.8 Verizon iPhone 4. SHSH Blobs helps in downgrading the iOS device to the current firmware if newer versions released.
To save SHSH for your iOS device simply connect it to the latest TinyUmbrella and click “Save All SHSH”
To save your SHSH via APPLE instead of CYDIA (the default) go into Advanced options and UNCHECK the box that clearly says: “Request SHSH From Cydia” then click ‘Apply Changes’ then select your device then click ‘Save SHSH’
Done! Your SHSH Blob will be saved on Cydia Server & on your local machine.
