Notcom has released TinyUmbrella 5.10.04 which supports tweaked iPhone 4S iOS 5.0.1 build 9A406. You can download TinyUmbrella 5.10.04 for Windows and Mac OS X from the link below…
TinyUmbrella lets you save shsh blobs which are needed to downgrade your iDevice firmware. Even though firmware downgrade is not possible yet for iPhone 4S, it’s always a good idea to save SHSH blobs for your device.
Although we cannot exploit/restore iPhone 4S SHSHs we still should save them just in case. I’ve just updated TU to support iPhone 4S 5.0.1b “9A406”.
