A few minutes ago Apple published iTunes 10.6.3, a new version of the program that is necessary for everyone who intends to update to iOS 6. Whether you have a developer account or install iOS 6 without one, you need this version of iTunes that you can download it from here. After downloading iTunes you can navigate to this page in which Apple is going to publish the opening keynote of WWDC 2012, but you will only be able to see it on the company's website.
