Here are a few words from the linked article:
Stanford has just released the iOS 5 incarnation ofiPhone Application Development on iTunes U, where the public can download course lectures and slides for free. Some of the most talked-about features of Apple’s latest operating system include iCloud, streamlined notifications and wireless syncing.
