IOS 9.2.1 has been successfully escaped and the jailbreak tool has not been released.
Luca Todesco, the god of jailbreak, has just posted a screenshot of his successful jailbreak against iOS 9.2.1 on his Twitter, saying that he has successfully run the Cydia program on iPhone 6 running iOS 9.2.1. However, Todesco has not released the tools for the successful jailbreak of the iOS 9.2.1 system, at least for the time being.
However, even if Todesco succeeds, it doesn't mean that we will have a jailbreak tool for the new system anytime soon. Todesco may suddenly change his mind, or he may have to wait for other teams to release jailbreak. At present, the system version number of Apple jailbreak stays at iOS 9.0.2, while since iOS 8.1, Apple has blocked the jailbreak vulnerability, making it impossible for the jailbreak to be carried out for the time being.
