I am trying to upgrade to iTunes 10.1 on my brother's computer. He has a powerbook g4, 15 inch, running OS 10.4.11.
When we "Check for Updates" in iTunes, we get a message saying that this version of iTunes (9.2.1) is the current version. When I run software update, it says all software is up to date. When I tried downloading iTunes 10.1 straight from the apple website, it downloads and opens, but I cannot open the installer - I get a message saying "Couldn't open, this package type requires OS 10.5"
I am afraid to erase iTunes completely and start from scratch, because my brother has an iPhone and does not want to lose the backup files, as his boss accidentally erased all of his media from his phone, including pictures that he doesnt have saved anywhere else.
powerbook g4 15in, Mac OS X (10.4.11), itunes 9.2.1

There is no legit way to downgrade.

itunes 10 requires Mac os 10.5.8 or later.

If the iphone has ios 4.2.1 software, then it requires itunes 10.1
Oh, I have it installed on my netbook, and thought I had installed it on my powerbook as well, but upon checking, I am still running itunes 9.2.1
Okay, well, another question then: My brother has an iphone 4 (I think, it could be a 3GS) and his powerbook will not recognize it, saying that it needs iTunes 10 - is there anything that he can do, short of upgrading to os 10.5?
Thank you for your help. I have one final question - is there a way to revert the iphone back to the older version of iOS that worked with 9.2.1? He was using it up through Christmas time, and I think his boss must have updated it to the new version of iOS when he took it, which caused it to not work with his computer anymore. He doesn't use the computer regularly so he doesn't want to dump money into the newer OSX if he doesn't have to.
