Your previous post which linked information from 2006, this was prior to 2006, it did not work.
Are you having reading comprehension issues?
The first iPod was released on Oct 23 2001, the page you linked in the internet archive was from 2006, so between those times, that page did not exist, and iTunes was forcefully incompatible with all hardware not made by Apple. They sued odioworks for making software that synced to the iPod http://en.wikipedia.org/wiki/A...
They got very mad and did something to Palm when their Pre faked being an Apple device, but it must have been short of a lawsuit as I cannot find info about a lawsuit:
Yes, you could bypass iTunes if you had another device, they even gave you a way to strip their DRM, but it required burning a music CD then reripping the song. Later on, they removed the DRM, but early iTunes had DRM to prevent the use of the music on anything but an Apple device.
Now, Apple iTunes did not allow other hardware prior to 2006, if you can show ANYTHING that says otherwise (from before 2006) than you can say you proved something, but your link quite clearly shows that the page hosted on archive.org is from 2006, not earlier.
