A new version of the extremely useful tool for jailbreakers, TinyUmbrella 5.10.06, has been released and it’s now supporting iOS 5.1 beta 2 and beta 3.

There was also an issue with the UI that was sometimes locking when you pressed the ‘Save SHSH’ button, and that has apparently being fixed too.

In case you’ve never heard of TinyUmbrella, the app is used for saving the SHSH blob file. When you restore your iDevice (after a jailbreak), iTunes verifies your restore and see if you are allowed to restore to the version you are requesting. having those SHSH files saved, you’ll be able to restore, or downgrade, forever.
