The well-known hacker iH8sn0w reported that he discovered an iBoot vulnerability for devices on the Apple A5 (X) chip. The vulnerability found will allow creating an “eternal” jailbreak that will not depend on the iOS version.
Looks like all my A5X devices are now fully untethered jailbreak for life
The Apple A5 chip powers the iPhone 4s, iPad 2, iPad mini, iPod touch 5 and Apple TV 3G. The A5X chip is used in the iPad 3. All of these gadgets are theoretically susceptible to hacking using the vulnerability found by the hacker iH8sn0w. In addition, the discovered vulnerability can help to find a “hole” in iBoot for the A6 and A7 processors.
iH8sn0w is not going to use the vulnerability it found to jailbreak A5 (X) devices yet.
