i0n1c (Stefan Esser)

i0n1c is very famous as security researcher for iDevices. In the jailbreak community known as i0n1c and real name is Stefan Esser, released video clip showing his  iOS 8.4 beta 1 installed iPhone running unique Cydia application as the latest. It was the new concept for iOS 8.4 jailbreak because most of the Developers failed to release proper version for beyond iOS 8.1.2 version. So iPhone & iPad users could make hopes for iOS 8.4 full version Cydia installation. Finally, it was able to jailbreak iOS 8.4 version. Pangu, TaiG and PP Jailbreak teams did it successfully. These three teams followed Stefan Esserís method to find jailbreak tool for iOS 8.4.
