I just updated my iPad mini to the latest version of iOS. This release is supposed to fix the passcode lock bug but a different variety of it was discovered after the update.

Here are some snapshots of my iPad mini updating to iOS 6.1.3. I still haven't updated my iPhone 4S because its currently jailbroken.
