No doubt, that iOS 6 is the most advanced and most sophisticated mobile operating system released by Apple. With a lot of new features, and it's worthy to update your iPhone, iPad or iPod touch to iOS 6.
But all of you know that iOS 6 is just released, and the iPhone jailbreak developer team hasn’t released any statement for iOS 6 jailbreak. As jailbreaking enhance the user experience, and give many features without them iOS 6 with 200 new features is still boring, like you can't change your theme without jailbreaking, you can't rum cracked apps and many more things.
Sometime users update their iPhone without knowing the consequences, and when they realize their mistake then it becomes to late, special people who use gevey sim or ultrasn0w to unlock their iPhone, as you know that unlocking depend on baseband of iPhone and once baseband was updated it can't be downgraded, so these kind of users can't do anything except waiting and this wait can be so long, may be more than 6 months. And something users trapped by the iTunes, as iTunes was continuously showing the message new version is available, and people click on update button without knowing the result of their action.
More Apple doesn’t allow you to downgrade your device once you update it. Bur dev-team or jailbreak developer team how even manage to downgrade your device, but to do so you must have to save your shsh blobs.
How to Check My SHSH Blobs are Saved?
To check your All you need to download tiny Umbrella. When tiny Umbrella opened just connect your Apple device with your computer and click on save shsh and see which firmware Shsh file is saved for your device. To understand it, see the below image.

How to Downgrade iOS 6 to iOS 5.1.1 or 5.0.1, the 2nd method :
In this method I will tell you that, how can you downgrade iOS 6 back to iOS 5.0 or 5.1.1 with the help of tiny Umbrella.
Step 1
ownload Tiny Umbrella. Run TinyUmbrella.exe. If Windows show any Firewall notification, select both check boxes and click Allow Access. (See snapshot below)
Step 2: Your iPhone, iPad or iPod should be connected to PC and make sure Tiny Umbrella has detected the type of device and its iOS version.
Note: Also save your iOS 5.0.1 or whatever iOS version you are running save its SHSH Blobs by clicking on Save SHSH. This will ensure we can downgrade back in case something goes wrong.
Step 3: Click on Start TSS Server and make sure it does not give any error.
Warning: This is very important! If you face any error till now DO NOT continue. Your restore will not work if the TSS server cannot be started.
Step 4: Now run iTunes. We will have to manually update to iOS 5.0.1. Open iTunes hold down the Shift key (on keyboard) and click Restore. Browse for the iOS 5.0.1 or any other IPSW file.

Step 5: iTunes must give error 1013. We want this error because it ensures the baseband has not updated.
Click Ok and close iTunes. You can now skip to Step 7.
Important: If you get a 16XX error then try entering DFU mode by following Step 6 and then go back to Step 4. If you did not get error 1013 after restore, it means your baseband was updated. This happens when the TSS server was not running OR you updated without Tiny Umbrella OR you are using any OTHER device than iPhone 4
Step 6: (only if you get an 16XX error after restore) You need to put iPhone 4 in DFU mode. Hold down both the Power and Home buttons for 10 seconds, then release the Power button and continue holding the Home button for another 5 seconds.
Step 7: Then your iPhone appears like the below screen shot. Don't worry about it just run TinyUmbrella.exe and "kick your iPhone from recovery mode"
