Apple released iOS 4.3.4 and iOS 4.2.9 so Notcom has updated TinyUmbrella to version 5.00.05 to support iOS 4.3.4 and iOS 4.2.9.
Since,Apple has fixed jailbreak exploit in iOS 4.3.4 update it is advisable to save SHSH blobs of iOS 4.3.3.
According to the official blog of Notcom-
Apple has finally come out with their ‘fix’ for the pdf vulnerability that JailbreakMe 3.0 uses to jailbreak devices. In proper good form, @comex has released a much better* fix for the vulnerability which also incidentally allows you to stay jailbroken
I’ve updated TinyUmbrella to save 4.3.4 SHSHs (as well as the other ones Apple is still signing). So grab the latest if you want to save 4.3.4 for nothing else than for the sake of completeness.
As always, if you are having issues, Uncheck “Request SHSH from Cydia” in the advanced tab!
