TinyUmbrella now supports iOS 5.0.1 for all devices. Added a few nag messages to remind people to update their settings. “Request SHSH from Cydia” and “Set Hosts to Cydia on Exit” should be disabled by users as soon as possible especially if you are having issues saving your SHSH.
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.
