Few days ago, Apple released iOS 5.1 beta for developers, and just few hours ago Notcom – the developer behind Apple’s devices tool TinyUmbrella – has released an update for his tool to support iOS 5.1 beta.
The known tool as u know used to save iOS SHSH blobs to be able to easily downgrade to a lower version.
From TheFirmwareUmbrella 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…
As all u know there’s no untethered jailbreak for iOS 5 or iPhone 4S so far. But it’s recommended to save your SHSH blobs just in case, you may need them in the future ….
