Apple's released yet another supplemental update for iOS 7, a little more than a week after the software was first released.

The 7.0.2 update, which went out Thursday morning, fixes a bug that would let users bypass the passcode security on the lock screen. That security issue was discovered just hours after the public update was released, and would give anyone direct access to applications and user data.

Apple last week said it was working on a fix, though did not offer an estimate on when it would arrive.

Along with the security fix, Apple says the update brings back the capability to use a Greek keyboard when typing in passcodes, something that was apparently missing in the early release.

Lock screens offer the primary means of defense against unwanted use of mobile devices. When introducing the iPhone 5S earlier this month, Apple claimed that only about half of smartphone users actually had passcode security enabled. That was just before debuting Touch ID, a new fingerprint scanning technology that's baked into the iPhone 5S and can unlock a phone without users having to enter in their passcode. The feature is expected to be included in all future iOS devices.
