Work on the iOS 5.1 Untethered Jailbreak Has Commenced

Hacker confirms he has started work on the latest jailbreak for the iOS community

Renowned hacker Pod2g (Joshua Hill) is “actively” working on an untethered jailbreak for iPhone 4S and new iPad tablets, according to his Twitter stream. Pod2g is the leader of an infamous group of hackers known as the Chronic Dev Team.

Answering a question addressed to him by one of his followers, French hacker Pod2g revealed yesterday that he was working to compromise the latest version of Apple’s mobile operating system, which powers iPhones, iPads, and iPod touch players.

Here’s the tweet exchange:

@po2g when do you think the new iPad jailbreak will be?

@pod18G Hi, I’ve no clue, but I’m working actively on finding vulnerabilities in 5.1.

The iPhone Dev Team was the first group of people to make a move towards providing a jailbreak for the recently released iOS 5.1.

Announced by their own leader (Musclenerd) via Twitter, and then on the Dev-Team Blog, the latest version of Redsn0w provides what is known as a “tethered” jailbreak for most iDevices.

A tethered jailbreak requires the device to be reconnected to a computer if a reboot is necessary (only to keep the jailbreak, not to actually restart the device).

The only device model that currently supports an “untethered” jailbreak is the old-bootrom iPhone 3GS, according to the hackers.

Work is now underway to find similar exploits for newer versions of the iPhone and iPod touch, as well as the second- and third-generation iPads.

While the iPhone Dev Team plans to update Redsn0w and PwnageTool when (or if) these exploits are found, the Chronic Dev Team will release a new version of their Greenpois0n (Absinthe) application that provides pretty much the same type of service, only via a different GUI (graphical user interface).

We’ll be keeping you up to date with the teams’ progress towards achieving this new milestone.
