Steven De Franco, the nickname is iH8sn0w is a necessary character in the jailbreak community. He owns very famous & valuable jailbreak tools too. iH8sn0w has many experiences about the jailbreak and creating jb tools too. He involves into the jailbreak with many ways since 2009.
Recently it has no any new tool release or new tool updates of his previous tools. He just found jailbreak methods and releases videos only. Actually, iH8sn0w motivates others jailbreak teams, when they are in trouble. Therefore, he is an important person to this field.
iH8sn0w successfully demonstrate iOS 10 jailbreak using the first beta version of it. He used iPhone 5C to complete it. iH8sn0w hinted to other jailbreak developers the possibility of iOS 10 jailbreak with this demonstrate. However iH8sn0w did not release any jailbreak tool for iOS 10. Here is the confirmed video of iH8sn0w iOS for 10/10.0.1 Jailbreaks.
Anyhow after iH8sn0w proved the possibility of jailbreak iOS versions, we found Cydia officially. At last, it has Cydia for iOS 10 to iOS 10.2 versions with Yalu102 jailbreak tool. Luca Todesco released it as Semi-untethered jailbreak for all the 64-bit devices. However, now it has many jailbreak tools for iOS 10 to 10.3.3 versions such as G0blin, Meridian, C0F3, H3lix, etc.
Until now iH8sn0w does not hint about the possibility of iOS version onwards iOS 11. However, after Ian beer found the iOS 11 exploit several jailbreak tools released to jailbreak iOS 11 & higher versions. Also KeenTeam demonstrated iOS 11.1.1 jailbreak at PoC 2017 as well as iOS 11 jailbreak using second beta of it privately at MOSEC 2017. However, there is no any jailbreak tool for iOS 11.2.2 yet.
Every time jailbreak tool’s developers in trouble finding a method to release JB tool, iH8sn0w helps them directly or indirectly. Here is the example.
When Apple killed iOS 9 and iOS 8.1 jailbreak, he involves directly to find JB method. For the first time, Apple introduced Rootless Jailbreak to prevent the jailbreak as a security update from iOS 9 version. At that point, all the jailbreak tool developers failed to find method, except the iH8sn0w. He demonstrated it on 10th September 2015 & released a video too. Then Pangu and TaiG got his method to find their own jailbreak tool. Pangu released iOS 9 Jailbreak. TaiG released iOS 8.1.1 Jailbreak. So, because of the iH8sn0w, we had these two jailbreaks.
Here is the iH8sn0w iOS 8.1.1 jailbreak demonstrate video.
Posixspwn for iH8sn0w Posixspwn is the most successful jailbreak tool of the iH8sn0w. It works to jailbreak iOS 6.1.6 to iOS 6.1.3 versions as untethered. The latest version is 1.0.8, and it is working both Windows and Mac operating systems. But, it has no any P0sixspwn tool update recently.
