How to bypass iPhone’s passcode-protected lock screen?

Circumventing iPhone Security with the Push of A Button

A tech savvy iPhone user has posted a video demonstrating a new finding; there’s an easily executable and potentially serious flaw in the iPhone password security function. Under the right circumstances, a simple press of the iPhone’s lock button will allow a malicious user to bypass the phone’s password protection and enter into the main phone app. Here, anyone can view the phone’s call history and stored contacts and listen to voicemail.

Wired.com’s Threat Level blog reports that Apple has not yet commented on the bug.
