Semaphore has updated TinyUmbrella, an app that saves your SHSH blobs, with support for iOS 5.0.1 and tentative support for the iPhone 4S.
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.
It may be a good idea to save your SHSH blobs using the tutorials below. We’ll update you with more information as soon as it becomes available.
