As the cat and mouse game between Apple and jailbreakers begins to heat up. Now, what started as a cat and mouse game has become more of a battle. Apple has certainly become more aggressive in the fight during the last few months. They recently implemented ASLR as a security measure to thwart hackers and code modders. They have also blocked Cydia access from inside their retail stores, and pressurised Toyota into removing their advertisements from Cydia.  Chpwn announced via Twitter today that Apple has blocked Saurik’s SHSH servers.




For those who aren’t familiar with SHSH blobs, they are necessary if you ever wanted to downgrade your iOS firmware to a previous version, that is from iOS 4.3.2 to 4.3.1.

UPDATE : It seems that Saurik noticed all the attention his downed SHSH servers were getting and decided to chime in. A few moments ago he tweeted that the server issue of saving new blobs was due to a code snafu, and not to Apple intervention.

Saurik had innovated a way to cache SHSH blobs for Cydia users. A simple file edit meant that users wouldn’t have to constantly remember to save their SHSH blobs with other 3rd party software.

Apple has also blocked access to their gs.apple.com server, which Saurik’s SHSH servers needed to function properly. Chpwn does mention that currently saved SHSH blobs are fine and usable, but moving forward users should find a different method.

How to fix this ?

Those of you that have been using TinyUmbrella or iSHSHit can continue to save SHSH Blobs through it. Chpwn also mentions that a “Submit my SHSH” could be on the way to Cydia to allow blobs to be saved locally and then uploaded to Cydia from the device.

This spreads the message that Apple is taking jailbreaking very seriously. It’ll be interesting to see how Apple addresses jailbreaking both publicly and in iOS in the coming months.
