i0n1c, whose real name is Stefan Esser, is a German security researcher. He developed Antid0te, an ASLR for jailbroken iPhones in fall 2010, but never released it, because iOS since 4.3 includes an implementation of ASLR. He developed an untethering exploit for iOS 4.3. He gave a version of the exploit that worked on iOS 4.3.1 to the iPhone Dev Team which updated redsn0w and PwnageTool to use it and released the new tools on 4 April 2011. sn0wbreeze was also updated to include his untether. As the vulnerability went unpatched in iOS 4.3.2 and 4.3.3, he updated his code later to support those firmwares. An iOS 4.3-compatible version was never released. His exploit was used in Pangu jailbreak.

On 19 April 2015 he released a YouTube video of a iOS 8.4 beta jailbreak, he has said he will not release it to the public.
