iOS 5 Beta Jailbreak Found Within 24 Hours

Apple’s new iOS 5 was successfully jailbroken within 24 hours of Apple CEO Steve Jobs unveiling it to the world.

According to an article on CNET (opens in new tab), iPhone jailbreakers calling themselves the iPhone Dev Team, and which is not actually affiliated with Apple in any way, revealed that iOS 5 beta was vulnerable to the limera1n exploit which targets the iOS boot software.

iPhone Dev Team member ‘MuscleNerd’ revealed that the exploit could be used to install the Cydia third party application on an iOS 5 device. The Cydia store, a haven for jailbroken iPhones, allows users to install applications that are not available from the App Store.

MuscleNerd also uploaded two photos to prove his claim. One shows a screenshot of the iOS 5 homescreen with a Cydia app store logo and the other shows the logo for the third party SSH iOS application.

The jailbreakers managed to successfully jailbreak an iPod Touch device on the beta version of iOS 5. Apple released the beta version of the new platform to developers during the World Wide Developer Conference.

So far the jailbreakers have only come up with a tethered solution which will require users to jailbreak their device every time they reboot it, but given the speed with which this vulnerability was found, it seems likely that someone will find a way to jailbreak the phone completely before long.
