iOS 4.2 Update Fixes Passcode Bypass Bug
The upcoming iOS 4.2 update, recently seeded to developers, fixes the recently-discovered keylock/passcode bypass bug. The bug allows any user with access to a locked iPhone to make phone calls, view/modify contacts, and send/view emails, by exploiting a simple bug on the “Emergency Call” screen.
Full details of security patches in this update will be announced upon release.
[Update] iOS 4.2.1 has been released.
