Wang said he used more than four software flaws for his latest jailbreak, which works on iOS version 6.0.2 on an iPhone 5. But Apple is likely to release iOS 6.1 soon, which means the company could fix the software to block Wang's exploit if it were disclosed.
The 6.1 version might also take away some other software bugs he's found, so "there's no point in sacrificing the many bugs" the update won't fix if the exploit isn't released, Wang wrote.
But jailbreak enthusiasts should not despair. There are likely more vulnerabilities in Apple's software waiting to be found, Wang wrote, "so while jailbreaking is getting harder, reports of its death are highly exaggerated."
