If you haven't already saved your ticket (via redsn0w's backup button), please do that now. That ticket is very important, and can't be reproduced should anything else fail. After you've done that...

If you update (NOT restore) your iPhone4 to 5.1.1 via iTunes (as opposed to OTA), your ticket should stay in place. Once the upgrade is complete, you should see a signal even without applying the jailbreak.

After the update (NOT restore! update is very different than restore), if you want to jailbreak again, just use redsn0w as normal.

You can downgrade from 5.1.1 to 5.1 on the iPad3, in case that ever becomes useful.

That's awesome, thanks for dropping by to say it worked! :)

Hi...that should now be fixed in 0.9.11b4. (Issues like that are why we advised in the main post to stay on the older redsn0w for A4 and earlier devices, but that should no longer be necessary as of b4).

Haha yes :)

You still need iTunes installed because redsn0w is using more and more of the dynamic library functions it provides.

The new update now includes that oddball 9A406 :)

If you get that warning about CoreFoundation or MobileDevice when you first launch it on Windows, this method will not work. I'm working on figuring out why that library loading is breaking for some people. (In the meantime, all you can really do is try another PC, or try a Mac...sorry!)

You're at the wrong window :) It's in Extras->Even More->Restore

redsn0w itself will apply Corona-A5 too if you want
