As mentioned in the earlier post, for now, it’s not safe to upgrade to iTunes 8.2 if you’re iPhone jailbreaker. The latest version of iTunes may affect the use of QuickPwn or PwnageTool to jailbreak. So, I suggest you hold off the upgrade.
However, it may be too tempted to hit the “Update” button when Apple informs you there is a software update. I know some of the readers have upgraded to iTunes 8.2 and experienced some jailbreak issues. They are searching for ways to downgrade it back to older version.
To downgrade iTunes, the process is very straightforward. What you have to do is to uninstall iTunes and then download & install the older version of iTunes.
For Windows User
For Windows user, simply go to Control Panel and uninstall iTunes via “Add/Remove Program”. If iPod Updater application is present, remove it as well.
For Mac OS X User
For Mac user, you can follow Apple Support’s article to completely remove iTunes. If you’re familiar with Terminal application, you can simply run the following command in Terminal app to delete iTunes:
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
Download the Older version of iTunes and Install it
Okay, now you should have the iTunes uninstalled. Next, you can simply head to oldapps.com to download the previous iTunes version and install it.
That’s it. Enjoy.
