The news came as a shock after Joshua Hill (p0sixninja) officially announced on his Twitter account that is no longer part of Chronic-Dev Team, team that develops jailbreak solutions for iOS. This is a great loses for the jailbreak community considering that he was a very active member and contributed to many of the jailbreak solutions that have emerged recently.
However, recently have been rumors that p0sixninja was interested in selling an iOS exploit to Apple. We can only speculate that p0sixninja either will be the new Apple employee or he sold an iOS exploit to the company and decided to leave Chronic-Dev Team.
Chronic-Dev Team still has skilled hackers, however p0sixninja was considered one of the best jailbreak developer. Such action usually opens the door for other jailbreak developers ready to take a step forward.
