TinyUmbrella was updated to version 6.12.00 for the iOS 6.1.2 firmware today that was released by Apple last week to fix the Microsoft Exchange issues plaguing devices and wreaking havoc on corporate networks. Luckily Apple never patched the iOS 6.1.2 firmware and as such it can still actually be Jailbroken with Evasi0n.
If you are Jailbroken on a previous version of iOS 6 it is recommended that you restore to iOS 6.1.2 and take advantage of the latest Jailbreak available before Apple releases iOS 6.1.3 to patch Evasi0n. Once you are running iOS 6.1.2 it is also highly recommended that you take advantage of the latest version of TinyUmbrella and save your SHSH blobs.
Why save your SHSH Blobs? Well…
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.
