Apple has just posted a new advertisement for its ‘magical’ iCloud service that can be used in any iOS device such as iPhone, iPad or iPod touch or a Mac computer. The 31 seconds TV commercial shows iCloud being easily used on an iPhone 4S to purchase a song and then the song automatically getting downloaded on an iPad and a Mac Air. The ad also demonstrates iCloud features such as Photo Stream and calendar syncing. And everything happened without a single word.
