Urgent action required for anyone that likes jailbreaking 4.3.1 or 4.3.2 and wants to do so in the near future.
For those of you unaware of the Apple firmware update policy, you can only restore firmware version that Apple approves. When you restore in iTunes, it goes to Apple’s web site and verifies if you are eligible for this specific version. This was solved by Cydia storing your SHSH (the is it ok to restore this version request response from Apple). This has been ok for the last year.
Semaphore (aka Notcom), the developer behind TinyUmbrella, has pushed a new update from TinyUmbrella to version 4.32.00 to allow you to save iOS 4.3.2 on iPhone 4, 3GS, iPod touch 4G, 3G and iPad, also TinyUmbrella 4.32.00 allows you to save SHSH for Verizon iPhone 4 running iOS 4.2.7.
As a reminder, to save your SHSH blobs, simply connect your iDevice via USB to your computer, launch TinyUmbrella, and click the “Save SHSH” button.
Apple is still signing 4.3.1. I suggest you grab the updated tiny umbrella v4.30.05 (Windows) (OSX) and save your SHSH locally for 4.3.1 on all your devices. For current 4.3.2 SHSH, use the latest tiny umbrella version (same instructions) (Windows) and (OSX).
To do this, go to advanced, uncheck “request shsh from cydia” and uncheck “set hosts to cydia on exit”. Then restart umbrella, go to show all shsh’s and save them all. In the logs you should see 4.3.1 come down. This will allow you to restore 4.3.1 or 4.3.2 through umbrella’s tss server if you need to.
Cydia’s SHSH system will hopefully be back up soon. When it is, I will post about it on this site. (Note: your older shsh’s are still safely stored in Cydia and are not lost).
Alternative to this is to install iSHSHit from Cydia, back up your SHSH and then email it to yourself. From there you can copy it to tiny umbrella’s SHSH folder.
