The TinyUmbrella utility has been updated to support iOS 5.1.
Notcom’s TinyUmbrella, the utility used to save your iOS device’s SHSH blobs for future firmware downgrades has been updated to support the recently released iOS 5.1 beta.
iOS 5.1 beta is the latest iOS firmware seeded to Apple developers. As of right now, there hasn’t been much information about what additions have been made. What we do know is the following: the battery issues persist, support for the iPad on the Sprint Network has been found, and it will expire on January 14th, 2012 (as per a tweet from iH8sn0w).
It was previously warned that jailbreakers should not update past iOS 5.0 and furthermore, it should be known that there is no way to downgrade as of right now. It still doesn’t hurt to save your iDevice’s SHSH blobs to have them on file just in case...
From the TinyUmbrella blog:
Before you ask; Yes a solution for the 5.x firmware nonce is being investigated… None of us have a working solution yet though. Hang tight. I have a couple trails and ideas I am trying out for 4.x baseband based restores to avoid 10xx errors. Until then save your signatures as you will never know when they may come in handy…
