if you have a windows, i guess you can just find someone else who had to download itunes and go through their downloads folder looking for the itunes installer .exe or whatever. if you have a mac, i dont know what to do, as an itunes 10 dmg would be pretty hard to find since it comes preloaded on all macs.
honestly i dont see anything wrong with it. sure its a little funky, but it works. nothing was really taken away
