A security loophole has been discovered in Siri, the much-touted iPhone 4S personal assistant. The default setting for the new A.I. is "On", meaning that when a user's phone is locked, anyone can pick it up, hold down the home button, and tell Siri to send texts and emails. Oh My!

However there is an easy fix. If you don't want Siri to work when the phone is locked, simply change the default setting from "Allow access to Siri when locked with a passcode" to "Off." Then check it to make sure the setting takes.
