Siri automatically launch picking up the iPhone 5.
The iPhone automatically senses that the device is being picked up and when the proximity sensor
indicates it is next to a head, like with a phone call, it will automatically start Siri.
To turn this on go to Settings -> General -> Siri -> turn Raise to Speak On
This menu also lets users choose a language, contact information and toggle Siri on or off. Just be
careful using this setting if you share your phone and have Siri calling you anything potentially embarrassing.
