More on x64 here:
I hate x64. x64 promised to increase the capabilities of computers. More memory, greater speed, bigger, faster, etc… And then, things stop working. Things I like. Things that nobody told me would stop working. Here's a list I started of things that don't work quite right in x64. I'm sorry to say that I discovered most of these the hard way :(

Update - The following article walks through a [lengthy] procedure for getting iTunes / iPhone to work on Windows XP x64 and Windows Server 2003 x64. While the procedure may work, it does not constitute support. Try contacting Apple if you run into issues. But, it is certainly better than nothing. Thanks for the link, lanceness.
