In order to use iTunes University, I had to install iTunes on my notebook that is running openSUSE 11.4. It is quite easy to get some old version of iTunes from http://www.oldapps.com/itunes.php but trying to install it on a 64bit machine with wine always failed.
In the end, I could install a 32bit version by doing the following:
rm -rf ~/.wine #(don't do this if you have other wine applications installed, it basically kills any previous wine installation) export WINEARCH=win32 wine ~/Downloads/iTunesSetup1021.exe
To start iTunes later on, it is sufficient to run the following command:
wine c:/Program\ Files/iTunes/iTunes.exe
Unfortunately, with most of the available courses on iTunes University, I get conversion errors. To circumvent this, I just download the respective courses and view them with mplayer:
cd ~/Music/iTunes/iTunes Media/iTunes U/ mplayer -vo xv <course file>
This is not too nice, but at least it allows me to view iTunes U courses without the need for an operating system I do not own.

Nice! I testing this in a few day, when i go back from Win 7 Pro to OpenSuse 11.4. :>
Can i syncronize my iPhone with the emulated iTunes?
Greeeeeetings from germany. And sorry for bad english.
Sorry, I do not have an iPhone. But from what I see, I would not expect the iPhone to work with iTunes that way.
i also used itunes to buy some songs, my conclusion was: do not download an old version, latest version from apple site works just fine (or even better than older version like 7.x) and yes, use the 32 bit installer. but I didn’t have to do the WINEARCH trick, it just worked by double-clicking the installer.
