Well there is a solution but I doubt people will like it
I run Tiger 10.4.11 on my iMac intel - its about 6 years old now so I will not ever upgrade since it still runs perfect and I don't want that to change.
I never thought I needed iTunes 10 but circumstances have now changed.
I was as surprised as everyone that it doesn't work on tiger.
However I needed it to use with a device so I did the next best thing.
I do have Windows XP running through Parallels Desktop
Decided to try to install it on there. Works fine, my iphone mounts and there you have it.
As absurd as it is - I am running iTunes 10 on my Mac that runs Tiger OSX through Windows XP with parellels.
Funny enough I can set the target for the library for my other iTunes that is in my Mac directory through the file sharing.
Crazy
21st century indeed.
