How to Downgrade iOS 4.1 on iPhone 4, iPhone 3GS and iTouch to iOS 4.0.1 / 4.0 and iPad iOS 3.2.2 and Jailbreak again with JailbreakME
Hey guys, since Apple has released the new iOS 4.1 to public yesterday I’m sure some of you (many of you) have updated their iPhones, iPads or iPod Touch devices to the newest Firmware and have lost the jailbreak.
Just so you know (FYI) at the moment there is no jailbreak available for iPhones and iPod Touch Devices iOS 4.1
In addition to that, Apple has already stopped signing the iOS 4.0.1 firmware Restore files. And what that means is this; You can NOT restore any firmware other than 4.1 with your iPhone or iPod Touch and / or to 3.2.2 for the iPad unless you have saved your SHSH blobs on Cydia.
If any of you have accidentally updated to the latest iOS 4.1 and lost you Jailbreak I have a solution for you… As long as you saved your SHSH blobs on Cydia Server you can go back to iOS 4.0.1 or lower by following the following step by step guide on how to downgrade your iPhone or iPod Touch iOS 4.1 back to to 4.0.1 or lower and the same goes for the iPad.
I have already written two very detailed articles / tutorial on how to downgrade the iPhone / iPod Touch back to the iOS 4.0.1 or lower and re-jailbreak it again with JailbreakMe. You will use the same tactic to downgrade from iOS 4.1

I have also already written very detailed article / tutorial on how to downgrade the iPad back to the iOS 3.2.1 or lower and re-jailbreak it again with JailbreakMe.

i just recieved an iphone 4 from a firend, it had 4.0.2 from the box, and i have updated it to 4.1 since there was no jail break is there a way to dowgrade or should i just wait for a new jailbrake for 4.1???
@Appu
If you didn’t have your SHSH blobs saved and if your iPhone was never Jailbroken before then you will have to wait until the release of the iOS 4.1 Jailbreak.
Sorry…
PS: It will not be long though, TRUST ME. Keep checking iPhoneTechie.com for the Jailbreak news and then follow my instructions.
I just jailbroke my iPhone 3GS and clicked make my life easier in cyida. I wanted to wipe the phone because I am giving it to my wives sister in brazil and she needs it to be jailbroken and unlocked to use it. Right after jailbreaking I went into settings and reset all settings (big mistake). The phone got stuck in a boot loop where it would only show the apple logo and would not start up. I follow the instruction but I still get the unknown error 3194 after trying to restore. I have change the host file like you said but not luck. Any other ideas. Please help.
