Apple thwarts Evasi0n jailbreak with iOS 6.1.3 update

Tools

Apple's (NASDAQ:AAPL) new iOS 6.1.3 mobile operating system update appears to spell doom for Evasi0n, the popular jailbreak enabling consumers to liberate their iPhones and iPads from the strict guidelines governing the iOS ecosystem.

Jailbreaking is a legal but warranty-voiding process that allows consumers to run unauthorized code, adding software, features and user interface tweaks not supported by the original manufacturer. Hacker collective Evad3rs released Evasi0n in early February, exploiting several iOS holes to create an untethered jailbreak; more than 7 million iOS device owners downloaded the hack in a matter of days.

CNet reports that iOS 6.1.3 patches the holes Evasi0n exploited, meaning consumers who install the Apple update will no longer be allowed to run the jailbreak on their device. (Apple's release notes even credit Evad3rs for uncovering four security holes fixed by the update.) Users can always opt against upgrading to iOS 6.1.3; once the update is installed on newer Apple devices, consumers may not downgrade to a previous version.

Redmond Pie states that consumers with older Apple devices powered by an A4 or earlier processor can still jailbreak iOS 6.1.3 using the latest version of Redsn0w. Unlike Evasi0n, Redsn0w is a tethered jailbreak, meaning that if the iOS device powers down, the user must reconnect it to the desktop to run the jailbreak again.

Apple released iOS 6.1.3 Tuesday. The update, first released as a beta to developers last month, also fixes a security vulnerability that allowed users to bypass the lockscreen and gain unauthorized access to call history, photos, messages, FaceTime and other services. iOS 6.1.3 additionally overhauls mapping information in Japan and now includes improved pronunciation for turn-by-turn directions as well as 3D images of buildings.
