It is now confirmed that Apple has blocked all of Saurik’s servers hosted at Amazon from accessing gs.apple.com i.e Apple’s SHSH server. This explains all the problems users have been facing while trying to save their SHSH blobs for iOS 4.3.1 / 4.3.2 / 4.2.7 using the latest TinyUmbrella. As a workaround, the only solution is to save the SHSH locally by accessing Apple’s servers with either TinyUmbrella or the free iSHSHit utility which is available on Cydia for free. Meawhile, a “submit my SHSH” is currently under works which would allow you to upload these signatures to Cydia too.

There is no official comment by Saurik himself on the issue but we’ll keep you posted as we have more on the matter. Stay tuned!
