Winocm manages to exploit A4 chip flaws, newer devices might not be as easy to crack

Jailbreaks become a rare commodity every time Apple decides to patch the holes with a new firmware update, and iOS 7.1 is no exception to the rule. Thwarting virtually every known vulnerability, the release of iOS 7.1 marked the death of evasi0n7.

But all is not lost. iOS 7.1 is on hackers’ radars, and one of them has already managed to jailbreak the firmware on 2010 hardware.

Hacker Winocm announced yesterday on Twitter that he managed to get an “iOS 7.1 untethered boot” running on a 2010 iPhone 4. The device is based on the A4 chip, which is known to be exploitable on every new firmware that Apple rolls out. Newer chips are much tougher to crack.

With his brief YouTube video (embedded above) Winocm offers evidence that iOS 7.1 can be jailbroken. However, it’s very unlikely that any new exploits he and his fellow hackers find in the future will be burned before Apple debuts iOS 8. Especially if the tinkerers manage to find holes that are usable on the newest generations of A-series processors, such as the A6X and A7.

Winocm has not released his jailbreak to the public, nor has he provided any indication that he will do so in the near future.
