downgrade ios 6 without shsh blobs
Apple has really beefed up the security on thier latest firmware and jailbreak hackers are facing a lot of problems to exploit this iteration. This means an iOS 6 jailbreak untethered will still a quite some time for a public release for all idevices. Here is a nice and easy tutorial for you to downgrade iOS 6 to 5.1.1 without even needing saved SHSH blobs on your idevice to still be able to use an untethered jailbreak. I have personally tested this method and it is working perfectly fine on pre-A5 bootrom idevices. Hit the jump for a complete tutorial. 

Compatible idevices :

  • iPhone 3GS,4
  • iPod Touch 4G 
  • iPad 2,3
How to Downgrade iOS 6 to 5.1.1 without 
SHSH Blobs Saved 

Step 1: Firstly, download iOS 5.1.1 for your iPhone,iPad and iPod Touch.
Step 2: Download redsn0w 0.9.15b1 for Windows or Mac OS X and jailbreak your idevice running iOS 6 (tutorial here) 

Step 3: Now and after jailbreaking your idevice, open redsn0w 0.9.15b1 and then move to Extras > Even More > Restore and then browse and locate your 5.1.1 ipsw file.

Step 6: Now move again to Extras > Even More > Remote.
Wait for some time as redsn0w will automatically perform a lookup of your shsh blobs in Cydia. if you still face any problems see the video tutorial below for further reference....
