iTunes 8.2 Messes up Jailbreak stuff! Steps to Uninstall iTunes 8.2 and downgrade to 8.1.1
Apple released iTunes 8.2 just in time for a probable iPhone 3.0 release at WWDC ’09. While iTunes 8.2 adds support for iPhone 3.0 goodness, it strips iPhone off of all the Jailbreak excitement! If you upgrade to the latest version of iTunes, you will no longer be able to Jailbreak the iPhone nor use SSH over USB. Apple changed some protocols in MobileDevice framework which resulted in panic-mode amongst the jailbreak community! The added security implemented some serious checks on the device hardware/software (security epoch, chipid, security domain, production mode, board id, bb chip id) before it actually lets the iPhone sync with iTunes.
So how do we get back to Jailbreak Awesomeness on a Mac?!
Step 1: Quit iTunes and iTunesHelper from Activity Monitor
Step 2: Launch Terminal and type in [Copy and paste it exactly without any extra spaces or else it might harm your system in a bad bad way!]
sudo rm -rf /Applications/iTunes.app /System/Library/PrivateFrameworks/DeviceLink.framework /System/Library/Extensions/AppleMobileDevice.kext /System/Library/PrivateFrameworks/iTunesAccess.framework /System/Library/PrivateFrameworks/CoreFP.framework /System/Library/PrivateFrameworks/MobileDevice.framework
Step 3: Type your admin password when prompted.
Step 4: Download iTunes 8.1.1 @ http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iTunes8/061-6171.20090406.i98u7/iTunes811.dmg
Step 5: Install iTunes 8.1.1 from the downloaded DMG file and replace iTunes Library file in username/Music/iTunes with your latest backup from the Previous iTunes Library folder
Step 6: Wait for a modified/patched MobileDevice framework before you even think of installing iTunes 8.2 again (if you don’t care about Jailbreak, go for iTunes 8.2)!!

It's good to have instructions on how to downgrade, but is there more to this than FUD? My jailbroken iPhone 3g just completed syncing with iTunes 8.2 – not a problem to be found…
If the iPhone is already jailbroken, you are golden! It is just that we cannot jailbreak iPhones using quickpwn / pwnage from now on! Patch is in the works though!

That's because you cannot tell the difference between iPhone 3G and iPhone OS 3.0

thanks for replying! I did the above until step 4: downloaded the 8.1.1 which wasn't recognized. tried this again without success. then found the questionmark in my toolbar indication for the itunes 8.2. checked for any left itunes in my applications, found an empty 7(tried to install, then found it to be 0). decided not to download/re-install the 8.2 again.
I have followed all of the step but am having problems with step 5. Can you please explain how to replace the iTunes Library folder and into which location (how to get there). I tried but am getting an error message of
The file "iTunes Library" file cannot be read because it created by a newer version of iTunes.
Please help I need to perform a jailbreak!
1 Go to Library and locate the iTunes folder and then drag it to the Trash. You can copy it to another place before deleting the folder.
2 Now launch your iTunes again and create your library again.

I have the same – The file "iTunes Library" file cannot be read because it created by a newer version of iTunes.
Tried deleting Itunes folder – still the same~
It may be resolved by putting the itunes icon in the trash (the one that wouldn't open)
Then go to applications->find another itunes icon->drag that to the desktop
First, I searched in spotlight for itunes folder then I've found a folder names "previous iTunes Libraries" ! I tried to replace it but I didnt the same result (maybe it work with you thou)
then I tried this solution and It worked fine for the music,movies,Tv shows and podcasts.but my application couldnt be relocated ! anyone know to solve this?
How do I re-upgrade to 8.2 without messing anything up?
I'm using 3.0 and iTunes doesn't recognize it!
Upgrading to 8.2 should be a snap. Just download 8.2 and install, it will upgrade the library without any errors…

Will this work on a unibody macbook? i know before there were reports of DFU not working on the Uni macbooks. I got itunes to recognize my iPhone in DFU mode using the walkthrough steps, but when I go to restore my firmware, I get error #1600
thank you! 🙂

You don't have to perform these steps anymore. Redsn0w does the trick!

I had to delete everything that was iTunes related on my HDD to get it working again. I lost all of my music and videos on my iTunes but it was worth it 😛 I didn't have many anyway. As long as my iPod can sync again without lagging out my entire MacBook!
i downgraded to 8.1 and now it says the iphone cannot be used because it require itunes 8.2 or later… but 8.2 wouldn't even recognize the phone so i want to keep 8.1. how do i fix this?
Use the latest vestion for iTunes and the firmware, it works…

my phone is unlocked using pwnage tool and when i first upgraded to itunes 8.2, my iphone (which is a 2G but has 3.0 firmware) was no longer showing up in itunes at all. so i downgraded to itunes 8.1. Now the itunes recognizes the phone again but says that it requires 8.2 or later. I don't want to upgrade to 8.2 again just to find that my phone no longer shows up in itunes… not sure what to do! help?
Well, since the latest unlocking tools work just fine with iTunes 8.2.1, I see no reason why you should be using it. Use 3.0.1 firmware and iTunes 8.2.1 and it should all work just fine!
Thank you for the auspicious writeup. It in reality used to be
a entertainment account it. Glance complicated to more brought agreeable from you!
