How To DOWNGRADE iPhone 4, 3GS, 3G, iPod Touch & iPad From 4.0.2 Back To 4.0.1, 4.0, 3.1.3, 3.2.1

PLEASE READ
Important: You must have saved your SHSH blob to Cydia by pressing the make my life easer button

Step 1 Download the firmware you wish to downgrade to:
http://www.felixbruns.de/iPod/firmware/

Srep 2 We now need to redirect iTunes server:
#1 Left click on wordpad and run as admin
#2 On the top left click file then open
#3 In the top bar type this in
C:\windows (Then press return)
Now click in to the System32 folder
Then click in to the etc folder
Now on the bottom right click on the drop down bar and click on all documents
Click on the hosts file at the top
Copy and past this just under the local host text just like in the video.

74.208.105.171 gs.apple.com

Step 3 Set your iDevice in to DFU mode
#1 connect your device to pc
#2 Open up iTunes
#3 Hold down power & home button at the same time for 10 seconds then let go of the power button and keep hold of the home button for a further 5 seconds iTunes should now pop up with a restore message
#4 Now shift click on the restore button this will allow you to search for the firmware you saved to the desktop.

Your device should now be downgrading !!

IMPORTANT
If you get an error message like 1015 0r 1004 DO NOT PANIC you just need to kick the device out of recovery and you can use: Tinyumbrella for this.

I have iPhone 4 4.3.3 and its not unlocked so I need to downgrade to 4.2.1 I do not have the SHSH Blops saved will I be able to downgrade.

[BakkarTech]

@Prashamshah ok well there is not point to downgrade if you are not on the right baseband cause you can not unlock but you can still jailbreak on 4.3.3. Any way there is this thing called Gevey Sim and it cost like 15 bucks off ebay and it unlock any baseband check out some videos on youtube.
