Apple has never approached the hackers to confront them with the jailbreaks, they said, adding that it would be interesting to know what Apple thinks of their work.
"Apple hasn't sent us as much as a cease-and-desist," Wang said, adding that he is not worried that Apple will try to stop them.
Apple should be happy with the jailbreaks, Bassen said, emphasizing that there is a lot of research that goes into jailbreaking an iOS device, which Apple otherwise would have to pay for. "It is free security research, and security research is not cheap, it is expensive," he said. "So they probably are happy."
The amount of work and sleepless nights involved in jailbreaking won't result in paid jailbreaks in the future, the hackers promised. "We won't ever charge for jailbreaking, that is a bad idea," Cyril said.
