Early today we told you that Apple has stopped signing SHSH blobs of iOS 4.0.1 and iOS 3.2.1, So Notcom has updated his popular tool "TinyUmbrella" to be able to save SHSH of iOS 4.0.2 for iPhone / iPod Touch and iOS 3.2.2 for iPad.

A few hours ago Apple has blocked the digital signature for the firmware 4.0.1 and 3.2.1 , so now it is impossible to restore to an earlier iOS version. From now users can't save SHSH files to Cydia or Apple for iOS 4.0.1 and 3.2.1 or lower.
so those who upgrade to firmware 4.0.2 will no longer able to restore or unlock their iPhones, in addition who upgrade his iPad to 3.2.1 will no longer able to unlock his iPad.
