Just yesterday, Apple released iOS 4.3.4 for iPhone, iPad and iPod touch. Subsequently Notcom, developer of TinyUmbrella updated the software to v5.00.05 which now allows us to save iOS 4.3.4 iPhone, iPad and iPod touch SHSH blobs on our Windows and Mac computers.
A word from the developer:
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.
If you're alien to this concept, you'll probably be wondering why you need to save these SHSH blobs and stuff. Basically, you need saved SHSH blobs to downgrade iOS firmware to an older version. Saving SHSH blobs of iOS 4.3.x right now is important as once iOS 5 gets released, downgrading from it will be impossible.
Apple is currently signing iOS 4.3.3 as well. If you're looking to jailbreak iPad 2 iOS 4.3.3, it is imperative that you download TinyUmbrella v5.00.05 right now and save the SHSH blobs, before Apple stops signing them and you are left with no way to downgrade iOS 4.3.4 to iOS 4.3.3. If you have any other iOS device, just save iOS 4.3.4 SHSH for the sake of completing your SHSH collection.
