Save SHSH for 5.0.1 with TinyUmbrella 5.01.00 – MuscleNerd begins work on iOS5 downgrading
Today, @notcom has released TinyUmbrella 5.01.00 which adds tentative iOS 5.0.1 support. Using this new version of TinyUmbrella you can save your SHSH for 5.0.1. Even though you can save your SHSH, there is still no way to downgrade using your SHSH because of Apple's blob monster.
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 5.0.1 SHSH. I have added tentative support for at least saving 5.0.1 SHSHs for iPhone 4S but as of now we are unable to use them fully. As soon as more information is available I will update.
