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.

HELP? Thanks.

powerbook g4 15in, Mac OS X (10.4.11), itunes 9.2.1
