TinnyUmbrella 5.01.00 is Available to Download for Windows and Mac
TinnyUmbrella tool is used to save SHSH blobs on your iPhone, iPad, iPodTYouch and Apple TV to help you to downgrade your iDevice rom higher firmware to older one. With release of iOS 5.0.1, Notcom has released TinnyUmbrella 5.01.00 to save SHSH blobs on iDevices running with iOS 5.0.1.
TinnyUmbrella release notes:
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.
