While away from home, I updated my iPod Touch (2nd gen.) to iOS 4.2.1 using a MacBook Pro running MacOS 10.6.3 and iTunes 10.1. I returned home, plugged the iPod into my PowerMac G5 with MacOS 10.4.11 and iTunes 9.2.1 and, yup, got the message that I will need to install iTunes 10.1 if I want to sync with iOS 4.2. Of course, iTunes 10.1 is not compatible with MacOS 10.4.11.

I would gladly downgrade the iPod Touch to iOS 4.1 but I cannot find it on the Apple website. I do have a file "iPod2,14.1_8B117Restore.ipsw" in the iPod Software Updates folder in iTunes which might work, but as the iPod Touch is no longer recognized, I do not know how I would do that.

Any help appreciated.

    If you searched this forum for downgrading you would have found that there is no legitimate way to downgrade the iOS.

    Another option you have is upgrading your computer to 10.5 Leopard and also iTunes 10.1

    I have several friends with PPC's that are running Leopard just fine.

    Thanks for the replies.

    I did search the forums for "iOS 4.2", "iTunes 9.2.1", "iPod Touch" etc. but I did not use the term "downgrading". So I didn't find the answer to my question.

    I am not a big fan of Leopard, especially as there are Classic applications that I still use (no Classic in Leopard), but the PM G5 has more than enough hard disk capacity to install Leopard on a separate partition or drive so that I can run iTunes 10.1. If rebooting is a PITA, then I can use the MacBook Pro (running OS 10.6) to sync the iPod Touch.
