A new version of TinyUmbrella has seen the light, it is the version 5.01.00 which brings support to save the SHSH blobs of iOS 5.0.1.
To save SHSH files of iOS 5.0.1 it is useless (for now). Recall that no longer enough to SHSH saved to downgrade version. Although there is currently no possibility to downgrade the initial IOS version 5, you can update this by the SHSH blobs of the iPhone 4S store and retrieve. In addition to securing other IOS devices SHSH blobs for iOS 5 and 5.0.1.
Even though there is still no working solution for restoring 5.x on iPhone 4S I have released a 5.01.00 so you can at least save SHSH 5.0.1. I have added at least tentative support for saving SHSHs 5.0.1 for iPhone 4S but as of now we are unable to use them fully.
As soon update as more information is available I will.
If you are waiting for an untethered jailbreak or more generally the possibility exists that you want to perform a downgrade in the future, I recommend you to save your SHSH blobs of your device. Even if the files are currently not sufficient to perform a downgrade, you should save the SHSH blobs for safety’s sake. The Dev-Team has been working for quite a long time working on developing a new opportunity for a downgrade.
In addition, even the SHSH assurance program “iSHSHit” from Cydia equipped with an update to version 1.0.13 and can now be downloaded there. Even with this program you can save the SHSH blobs of your device, but due to lack of opportunities not to jailbreak the iPhone or iPad 2 4S.
Nevertheless, meanwhile, still unclear whether the jailbreak community will ever find a new way for a downgrade from iOS fifth Nevertheless, we recommend all users to go safe and secure your files.
