So when I first saw these screenshots, I was thinking those guys at Aspect software have done a great job with wifitunes. But no the screenshots are actually from a special build just for Windows mobile 5 devices. Apple are really gunning for the mobile market.
Looking at the blog post, there seems to be no iTunes sharing (zeroconf) but iTunes store ability seems to be just around the corner. This is all pretty straight forward when you consider that iTunes has had Mobile phone syncing cabilities since 4.9. But lets step back for a moment, maybe the whole thing is a hoax? Engadget are certainly considering it. I personally think its a early build and maybe true, specially if you consider the next Razr could include iTunes.
