Breaking: Reports of 1.1.1-to-1.0.2 iPhone downgrades trickling in

Remember that bit where I said upgrading from 1.1.1 to 1.0.2 was a one-way trip? Looks like I spoke prematurely. Tonight, reports are trickling in about successful 1.1.1-to-1.0.2 iPhone firmware downgrades using this method described at the "iPhone Devteam" wiki, which relies on a combination of firmware-fu and the INDependence software. TUAW reader skwasha tipped us off to an ongoing conversation at the hackint0sh forums that got the ball rolling on this.

I have not yet been able to confirm this downgrade so let us know in the comments if the method worked for you or not.

Update: After downgrading your iPhone will most likely not work as a phone. But you'll be able to use it with third party apps and WiFi. Developing.

Update 2: More detailed instructions here at Nate True's blog.

Update 3: This method is now called "pulling a kmac" after the original poster who figured this out.

Update 4: If you're getting the "Please Connect to iTunes" thing, you'll need to set some environmental variables. You can do this with either iBrickr/iphoneinterface or with iPHUC. Instructions for both at Nate's blog.

Friends:

Can someone define what "jailbreak", "flash the baseband" and "virginize" mean exactly?

Thanks amigos -Migs

I have been using it with the 3rd party applications called Installer and everything works fantastically. I ahve installed many 3rd party applications and i have one major question: Will I lose everything if I upgrade my phone to the firmware version 1.1.1???? Also could someone help me to give me all the step that I have to do to upgrade my iphone to 1.1.1.

I would really appreciate a complete comment from one of you as I am really a computer genious.

I just managed to buy a new iphone and it has a 1.1.1 firmware already on it, is there a way to downgrade it and unlock. Please note that i didn't upgrade to a 1.1.1, but accidentally brought the phone with it. I also don't have an AT&T connection and am trying to use it on Vodafone in India.

Any help would be highly appreciated!

Just went back to 1.1.1 Edged did not work after reverting back to 1.0.2

I think At&T has set up a cookie munster that disables edge on customized phones.

Will try again.

This feature lasted 5 days! Just today my iphone went bonkers. I went from 1.0.2 then to 1.1.1 then back to 1.0.2 after 5 days of enjoying the third party, on the first day my mail app disappeared... It was there but could not see it..after ssh into phone and purging everything in the mail.app folder it was restored.



Today my photos disappeared and when plugging the phone into itunes it came up with a max space of 250 megs storage and 55 available..Instead of reading the 8 gigs of max space..

Had to do a bootie call..After the restore..all is good but somethings not 100% with this hack but well worth the trip

All in all, I'll just restore if it happens again..Nothing beats the apptap and everyting you guys are doing..Just thought I'd give a heads up to the lab.

Anyone else have this problem?

Theory:
Apple needed to protect AT&T's exclusive relationship with them and found a way and an excuse to re-establish the exclusivity between
them. If they did not either brick or re-lock hacked iPhones, AT&T could sue Apple for a breach of contract. It would be a bigger loss, financially, to lose AT&T than to lose a few thousand consumers.

Well I tried downgrading back to 1.0.2 using the ibrickr iphoneinterface.exe so i can reboot normally but I accidentally hit the wrong command. I entered "setenv auto-boot TRU" instead of "TRUE" and now my iphone can't start up. When I try to turn it on all I see the apple logo and the lines that move in a circular motion and then the phone automatically turns off and turns on and repeats the same process. I'll paypal $100 to anyone that can guide me through the process of fixing this.
