Download TinyUmbrella for iOS 5.0.1 and iPhone 4S
Notcom, the person behind famous tool TinyUmbrella has released TinyUmbrella 5.01.00 for Windows and Mac. With latest update you can save SHSH blobs of iOS 5.0.1 and supported devices including iPhone 4S. SHSH Blobs are used to downgrade your device firmware to older version.
Although, a workaround hasn’t yet developed to downgrade from iOS 5 and saving SHSH blobs wouldn’t matter much right now but you’ll need it whenever some solid method to downgrade will hit the interwebs.
This is what Notcom said in his blog post:
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.
New version of TinyUmbrella provides tentative support for iOS 5.0.1 SHSH blobs on iPhone 3GS, iPhone 4, iPhone 4S, iPad 1, iPad 2, iPod touch 3G and iPod touch 4G.
