Apple pushed an update to iOS (7.0.2) to fix the lockscreen bypass bug and also re-introduce the Greek keyboard option for passcode. It’s a minor but very important update that you should switch to.

If you’re on iOS 7 (or iOS 7.0.1 for the new iPhone), you just have to go to Settings → General → Software Update. You can do an OTA; it should take you just about a few minutes to get it done. The update file is about 20 MB in size.

It’s necessary that you do this update because this one has a security fix: a prominent security fix that has been widely reported and therefore, well-known. The lockscreen bypass actually let someone access parts of your iPhone/iPad even without entering the passcode. Arguably, it was tough and it took some knack to get it right but once inside, the user could actually access apps. Pretty risky.

Besides this, there have also been other issues with iOS 7 security – some of them stemming from the default feature-set, some of them actually real loop holes in the code. We wrote about a few of them.

As is always the case, there are bound to be errors, issues and security holes in every major iOS upgrade. This happened with iOS 5, 6 and it’s not surprising that it happens with iOS 7 too. Fortunately, none of it is life-threatening unless you toss your iPhone or iPad carelessly to fall into others hands’. Apple mostly works quitely and quickly on security issues and the latest update has been pushed to make up for the holes in iOS 7.

For the ones that are looking for jailbreak-related advisories regarding the update, MuscleNerd has tweeted that it’s safe to upgrade to iOS 7.0.2. Apparently, the existing exploits that are being tested for a JB in the near future are still wide open. This means you can update to iOS 7.0.2 without regretting the loss of a JB opportunity later.

If you’re facing OTA update issues and would do it the iTunes-way, you can download a custom IPSW or update through iTunes directly.
