Update: iPhone 5 Has Voice-based 'Virtual Assistant'

It's official: The iPhone 5 features Siri, a voice-based virtual personal assistant.

With it, you'll be able to set your phone's alarm, schedule events on your calendar, create reminders for yourself, get restaurant recommendations and more--just by speaking into your phone.

According to Engagdet, you can even ask Siri seemingly not-specific-enough questions, like "Do I need a raincoat today?" The device will respond with something like "No, it's sunny outside." 

Apple even covered the inevitable question of "Who are you?" Engadget reported that the response will be: "I am a humble personal assistant."
