iPhone bug enables FaceTime, shows names on locked phones
iPhones that have been password-protected and have voice dialing deactivated can still make FaceTime video calls, as well as disclose basic information about a person's list of contacts.
The security loophole, which is present in the latest version of Apple's iOS 5.0.1 software, was discovered earlier this week by Canadian tech writer Ade Barkah, who posted details about it on his blog. CNET confirmed it working on three different iPhones, including the iPhone 4 and 4S.
In short, it works like this: If you've got your iPhone set to what are basically the highest security settings--passcode required immediately, as well as voice dial and simple passcode off--you can still make FaceTime calls through the iPhone's emergency call feature using Voice Control.
