He worked on the jailbreak with jailbreakers Joshua Hill (@p0sixninja), David Wang (@planetbeing) and Cyril, who did not provide his last name and is also known as (@pod2g).

The jailbreakers expect their latest software to be downloaded about a million times, they said during a press conference following the announcement. In the past, the jailbreaks were downloaded about half a million times, but that number is increasing, they added.

The jailbreakers don't expect that Apple will roll out a quick fix for the latest iOS hack. "Of course, they are going to patch things. But I'm not sure they will release a new version of iOS just for this. I think they will wait for iOS 6," said Cyril. The jailbreakers -- who met each other in person for the first time during the conference -- expect that a beta version of iOS 6 will become available soon.

They denied rumors that they have already started working on an iOS 6 jailbreak. "We are actually not working on that," Bassen said, adding that "it is always good to have an exploit in the drawer," hinting that they have other jailbreaking methods lined up that can be tried on the next version of iOS. "There is a good chance we will use one of them," Bassen said.

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.
