The iOS Dev-Team has coded two utilities that provide an untethered jailbreak for the latest iteration (iOS 4.3.1 ) of Apple’s mobile operating system.
The tools – PwnageTool 4.3 and redsn0w 0.9.6rc9 – are currently available for a number of Apple devices, including:
- iPhone3GS
- iPhone4 (GSM)
- iPod touch 3G
- iPod touch 4G
- iPad1
- AppleTV 2G (PwnageTool only)
Unfortunately, the untethered cracks aren’t compatible with the iPad 2, as the tablet requires a bootrom or iBoot-level exploit to install – and the device isn’t susceptible to either the limera1n or SHAtter bootrom exploits.
The 4.3.1 untether exploit was coded by Stefan Esser (@i0n1c on twitter), a security researcher based in Germany.
“Stefan has a long history of vulnerability research, and ironically his first contribution to the iPhone jailbreak community was improved security – last year he beat Apple to the punch and implemented ASLR for jailbroken iPhones with his ‘antid0te’ framework,” a Dev-Team blog post explained.
“We’re happy to see that Stefan then turned his iPhone attention over to an untethered jailbreak exploit!”
