The developer of TinyUmbrella @NotCom has updated TinyUmbrella to version 5.10.06. In TinyUmbrella 5.10.06 we see support for saving iOS 5.1 beta 2 SHSH blobs and even iOS 5.1 beta 3 SHSH blobs.

Besides support for saving various iOS 5.1 Beta SHSH blobs NotCom has fixed a nasty UI locking bug that happened when you clicked the ‘Save SHSH’ button. While he has managed to fix this bug, NotCom concludes that there is a flicker that happens in the saved SHSHs window due to the way he patched the UI locking bug.

And as the untethered jailbreak is on the way, it's important to Save iOS 5.0.1 SHSH Blobs Right Now For Future Jailbreak.
