    Weng Chin points out something he describes as a security flaw in the iPhone 4S with Siri. In this video, Chin demonstrates that a user can make phone calls from the iPhone 4S even while it is protected by the iPhone:

    At 1 minute and 5 seconds in the video, Chin shows using Siri to make a phone call despite the iPhone 4S being locked. This seems to be by design, however.

    Having Siri enabled while your phone is locked allows for you to continue to have hands free usage of your phone, even when in a locked state. Apple does offer you the ability to turn Siri off on the Lock Screen, if you prefer more security over convenience. In previous iPhones without Siri, users could similarly dial arbitrary numbers using Voice Dial even when the iPhone was locked. Apple similarly offered an option for Voice Dial to be turned off on the Lock Screen only.

    There is an option to switch this off.

    Under Passcode lock ''Do not allow access to Siri when locked with a passcode'.

    You obviously have that option selected.

    What about voicemail? Can that be checked when the iPhone is locked?

    LOL, they went to all that trouble to create a video when it's obvious you can toggle this feature on and off... :D

    I think people should be a little more careful before labelling something a "flaw".

    And here starts the search for the next Apple-Gate. Will they unlock the eighth chevron and where will it lead?!

    Why is this news? My iPhone 4 did this out of the box, although I do not recall whether or not there was an option to turn off that specifically on iOS 4.x

    As they point out, you can disable Siri functionality while, how is this a security issue?

    Can you do other things like schedule a reminder or do a search with Siri when the phone is locked and password-protected?

    It seems like everyone these days is in a rat race to get videos online. The phone wasn't his and he obviously spent limited time on it. If someone posts a video they're automatically an "expert" but it's obvious to me he probably only spent minutes with the device before joining the rat race and wasn't aware this is a convenience function that can be turned off and not a flaw.

    We have to stop this "this-gate that-gate" trend. What are we gonna call it when Bill Gates gets involved in a scandal? "Gatesgate?" :D

    Unfortunately the scandal involved the gate to his front yard and it became known as Gatesgategate. :p

    For those saying iOS 4 already does this, Voice Control can only call people in your contacts list, not random numbers like is shown in the video.

    [edit] Never mind. I was wrong.

    Wrong. Voice Control on iOS 4 can also dial random numbers too except instead of saying "Call" you say "Dial". Call works for contacts while Dial works for random numbers.

    CALL [contact's name] = Will call your address book contacts
    DIAL [xxx-xxx-xxxx] = Will call any random number

    It works on 3Gs too

    Weng, the only security flaw is you, because you haven't made the effort to learn how to secure your phone!
