I have two problems - first, I just lost my iPad which was not password protected because I was sure this would never happen - how dumb! Is there any way to disable it?
Second, I double clicked my iPhone 4S when turning it on, and Siri has taken over! I can't use the touch method anymore, she instructs me to double click; I can't swipe the screen or make it larger or smaller, etc. How can I get out of this mode? Many thanks!!!
If you have not password protected it or installed Find My iPhone there is nothing you can do. See Reporting a lost or stolen Apple device.
Try a reset. Press and hold the Home and On/Off buttons simultaneously until you see the Apple logo. This may take 10 - 15 seconds and is the equivalent of a re-boot. You will not lose any data.
