It is Sunday, or Funday, we still waiting for the Evasi0n iOS 6 untethered jailbreak anytime from now, maybe after a few hours who knows ! But while we are waiting let us save SHSH blobs. Why it is important even when there isn't any jailbreak?
Simply, because these files are important to downgrade back to iOS 6.1 once newer firmware is released. So if you don’t save SHSH blobs for a specific firmware, ever being able to downgrade to that firmware is slim to none.
STEP 1: Download TinyUmbrella From Here on your computer then double click to run.
Step 2: . After the app is fully initialize, connect your device [any Apple devices] that can run iOS 6.1 then select your connected device [in the upper left hand] of Tiny Umbrella.
Step 3: Click on the advanced tab and unchech:
Save ALL Available SHSH
Request SHSH From Cydia
Step 4: Change the save SHSH directory to an SHSH folder. verify, and backup SHSH blobs in a more familiar directory.
Step 5: Click the Log tab for preparing to see the status of your save attempt.
Step 6: Click on Save SHSH and Tiny Umbrella will attempt to save the SHSH blobs for iOS 6.x [6.1 or the latest iOS Firmware]
Step 7: Save it to the directory you selected in Step 4 [a message that says SHSH Successively saved].
Step 8: Open SHSH folder, and verify that the SHSH blob for your device is there. Ensure that it is labeled with the correct device name, along with the proper firmware.
It is done !
