Apple has just opened up the iCloud.com web interface for developers. The website is in beta and features all new web apps for Mail, Calendar, Contacts, and more. In addition, it appears that iCloud.com will offer a portal for users to view their iWork documents that are stored in the cloud via iCloud. On top of all of this Find my iPhone is an integrated web application. As you will see, the interface for the website is very iPad and iOS-like. We also have a video walkthrough after the break.
