The first iPhone 4S ad has aired on TV and very prominently features Siri, the voice-activated personal assistant exclusive to Apple's newest handset. The ad shows several people talking to their iPhones, asking questions, looking up directions, setting up reminders -- all in very natural language. Siri itself doesn't appear until near the end of the video, though, so people who've never heard of the feature before may find this commercial somewhat confusing at first.
We've embedded a version of the commercial below (hat tip to Engadget) that someone filmed off their TV. The official ad hasn't shown up on Apple's site or its YouTube channel as of this writing, so we'll update this post later on when it does.
