Apple Releases iOS 4.0.2 for iPhone and iOS 3.2.2 for iPad to Patch PDF Exploit

Just a week after the PDF exploit was uncovered, Apple releases iOS 4.0.2 to patch the vulnerability.

The PDF security flaw was found on iOS 4.0 and 4.0.1, as well as, all versions of iPhone OS 3.1.x. The vulnerability allows hackers to complete control of iPhone by using a malicious PDF file. This iOS update is intended to fix the security bug.

Stay Away from the Upgrade if You need Jailbreaking

Unfortunately, the JailbreakMe, the browser-based jailbreak tool, also utilizes this security flaw to jailbreak iPhone running on iOS 4 and iPad running on iOS 3.2. That means, once you upgrade to the iOS for your iPhone or iPad, you can no longer jailbreak the device with JailbreakMe. So, if jailbreaking is imminent for you, DO NOT UPGRADE when iTunes prompts you.

Stay with iOS 4.0.1 for iPhone and 3.2.1 for iPad. But bare in mind that your device is exposed to an security hole and you need to take extra care when downloading PDF.

Upgrade the iOS if You think Security is more important

If you do not need jailbreaking, I highly recommend you to upgrade the iOS to the latest version for your iPhone or iPad. To upgrade, you can simply connect to your device to computer and upgrade it via iTunes.

As always, please leave us comment if you have any questions or anything you need further clarifications.

Update #1: Saurik, the creator of Cydia, will soon release a patch specially designed for jailbroken iPhone to patch the PDF security bug. Stay tuned.
