One of the trio is another ad about Siri. As in the first spot, questions are poised to the personal assistant-including a very timely one about the weather (especially if you live up north)-and Siri provides the answers quickly. Another spot shows how iCloud allows you to make changes on your handset for work or play, that will show up on all of your other devices. And the last ad deals with the new upgraded 8MP camera on the back of the Apple iPhone 4S.
Those handling the ad campaign of other handset manufacturers should watch these three spots and take some notes.
