Apple just released a new patch for iOS 7 that fixes a bug that allowed anyone to bypass the lock screen in the new iOS 7. The exploit involved swiping up on the lock screen to access Control Center, then opening the alarm clock. Holding the iPhone’s sleep/wake button brings up the power off option, and you could hit cancel, double click the home button, and have access to the multitasking screen. This would give anyone access to your photos, camera, email, Twitter, Facebook, or Flickr account.
Today’s update to iOS 7.0.2 purports to fix that, and reintroduces a Greek keyboard option for passcode entry.
