TinyUmbrella has been updated today to version 6.10.03 for the release of the iOS 6.1.1 firmware that Apple pushed to the iPhone 4S. If you have an iPhone 4S and you upgraded it to iOS 6.1.1 you should without a doubt download the latest version of TinyUmbrella and save your SHSH blobs as soon as possible.
I have said this many times, but I am going to repeat myself. Although the usefulness of saving your SHSH blobs is becoming less and less, the possibility that a new exploit could be found to once again re-open downgrading is pretty high. It is better to save your SHSH blobs in case you accidentally update to a new firmware version and a downgrading solution is found requiring them, rather than missing out on the downgrade because you were too lazy to save your SHSH blobs. Furthermore, saving your SHSH blobs allows you to re-restore to the same firmware version you are currently running, when Apple stops signing it.
Among other things NotCom has said he is still working on the mythical rewrite of TinyUmbrella and also a Cydia tweak (we will keep you posted on that). You can check out the official post for yourself below…
