So finally  Apple has cut the rob of iOS 4.3.3 signature support, several times we have recommend users to save the iOS 4.3.3 SHSH blobs, if they want to downgrade or restore their iOS devices because Apple has released the new version of iOS 4.3.4 which comes up as a killer of jailbreak tools. The SHSH blobs of iOS 4.3.3 is really important for iPad 2 owners because there is only a firmware version where they can jailbreak their device and Apple is in complete try to update their iOS devices to the newest iOS firmware where they have fixed the Safari Exploit which uses by JailbreakMe 3.0 to jailbreak the iPad 2 and all other iOS devices running iOS 4.3.3. This thing is really bad for those who had not save their SHSH blobs, and already updated their iOS firmware version to iOS 4.3.4 or any beta version of iOS 5, because on every downgrade to normal/stable version they need iOS 4.3.3 SHSH blobs.

The key member of iPhone Dev Team has announced late night through the tweet that Apple has shut down the window of iOS 4.3.3 signature registering, and now after this no one can save the iOS 4.3.3 SHSH blobs and downgrade their device to iOS 4.3.3 without SHSH blobs of iOS 4.3.3, we hope that large number of users have saved their iOS 4.3.3 SHSH blobs and didn’t stuck with Apple.
