Untethered Jailbreak for A5 Devices: Sandbox Issue Solved, ‘Saurik’ Offers 'Major Contribution'

Last week, Pod2g, the hacker responsible for the untethered jailbreak on iOS 5.0.1 for A4 devices, announced a Dream Team for the A5 untethered jailbreak on his blog. The team consisted of three of the biggest names in the jailbreak community - planetbeing, MuscleNerd and p0sixninja.

The team, apparently, just got bigger; Saurik aka Jay Freeman, a key jailbreak developer who is largely responsible for the creation of Cydia, has joined the fight. According to MuscleNerd, the team has already received some major contributions from Saurik.

props to @saurik for major contributions to the A5 version of @pod2g's untether yesterday! (still no ETA, but moving forward), MuscleNerd tweeted.

In an earlier update, Pod2g revealed that Apple sandbox on A5 devices was one of the main hurdles for an untethered exploit for A5 devices. However, according to another tweet from Pod2g on Tuesday, hackers seem to have resolved that issue.

@MuscleNerd @saurik And greetings to @planetbeing for the coding + research. Really great stuff to escape from the sandbox, Pod2g tweeted.

What is Sandbox?

Sandbox is a security mechanism, meant for separating running programs. It is frequently used to execute untested code or untrusted programs from unverified third-parties.

All the iOS applications from the App Store are sandboxed. On the other hand, apps available via Cydia are not limited by the iOS app security sandbox.

Although the team has made significant progress by solving the sandbox issue, a lot of work is still left. The untethered jailbreak for A5 devices is still in testing as it relies on having a developer account and can't be released publicly as of now.

For the time being, users are recommended to update their devices to iOS 5.0.1 before Apple comes up with another update. The A5 untethered jailbreak for will come for iOS 5.0.1.
