Untethered Jailbreak iPhone 3GS OS 3.1.3 Via Userland Exploit


Got a third-gen iPhone 3GS on iOS 3.1.3 and can’t wait to jailbreak it? We’ve got a treat for you! Yesterday, famous iPhone hacker Comex uploaded a video on YouTube showing an untethered jailbreak of a 3rd generation iPod Touch running OS 3.1.3. Not only does the video meet all the guidelines of a good jailbreak video as set by the iPhone Dev Team, but it also got the approval of MuscleNerd as being legitimate. Check out the video after the break.

As you can see in the video, the process of jailbreaking your device with this method couldn’t be any simpler. This new untethered jailbreak is web-based (userland), which means that you just need to point your browser to a certain link and your device is jailbroken! The exploit used here is apparently based on the security hole identified by two hackers Ralph Phillip Weinmann and Vincenzo Iozzo at the Pwn2Own contest. The end result: Jailbroken devices and happy users.

For those of you new to the platform and still unfamiliar with what jailbreaking is all about, it is the name given to the process of removing restrictions set by Apple on their iOS devices that prevent users from installing any apps or hacks from sources other than the App Store. Once jailbroken, your device gets the Cydia store installed and using that, you can install all sorts of apps, hacks and mods that help you take your device beyond its locked-down state that Apple ships it in.

Do note however that since userland exploits pose a serious potential risk to the users’ data, it is very likely that Apple will be pushing forth a new firmware soon to close this hole (3.1.4 or 3.2, anyone?). However, hackers would also not want to miss out on this opportunity, so our fair guess is that we may be seeing an untethered jailbreak for iPhone OS 3.1.3 sometime soon now.

Just days before this, GeoHot has also shown an untethered jailbreak for OS 3.1.3 and the much-hailed iPad 3.2 firmware. With this development, the list of devices that can be jailbroken on the latest iOS version has expanded.

We would again insist here that jailbreakers should avoid any firmware update and save their SHSH for iPod Touch 3G and iPhone 3GS via Cydia by choosing the Make My Life Easier option to secure their future jailbreaks.

Tried out this jailbreaking method on your device? Did it work out fine? Know of another, perhaps better way of jailbreaking it? Let us know in the comments below.
