Although Apple released an iPhone software update this week that fixed a bug that allowed people to access your locked device without a passcode, another similar vulnerability has been discovered.
In a video posted to YouTube, a user shows the latest update to iOS still lets you gain access to a locked iPhone.
However, it seems like the vulnerability only works on the iPhone 4 or 4S. The hack involves tricking the phone's voice control feature into dialing a number. (By "voice control" we don't mean Siri, we mean the iPhone's older voice control feature that you can access when Siri is disabled.)
TNW suggests a temporary fix: You can leave Siri enabled on the iPhone 4S or disable voice dialing on the iPhone 4 under Settings > General > Passcode.
