It looks like the iPhone lock screen provides just a marginal level of protection. [Jordand321] discovered a key combination that opens the contact app on a locked iPhone. Just tap the emergency call button, enter the pound sign three times (###), then tap call and immediately tap the lock key on the top of the phone. If this is confusing just look at the video after the break to see how it’s done.

You don’t get access to everything on the device. But this does give an attacker access to all of your contact data and allows that person to make any calls they desire.

[greenmymac] on the MacRumors forums recently exposed a security flaw that allows anyone full access to a locked iPhone running firmware version 2.0.2. The flaw works by entering the emergency call menu of a locked iPhone, and double tapping the home button. This opens the iPhone’s Favorites menu, allowing anyone in your Favorites to be called. From here, an attacker has access to your SMS messages and potentially your email or Safari browser. While we are sure that Apple has a patch for this flaw on the way in the next firmware update, there is a temporary way to secure your locked iPhone. Simply enter the Settings menu on your iPhone and enter General > Home Button and select “Home” or “iPod”. Now when you double tap your home button, it will navigate to either your home screen or the iPod screen. While this fix might be annoying for some, as of right now it seems like the only way to secure your locked iPhone.
