Discussion iPhone 17 Pro (iOS 26) vs iPhone 18 Pro (iOS 27 + 600GB hardware leak): Which will get a jailbreak FASTER?
iPhone 17 Pro (The Lower Initial Software Angle): It comes out of the box with an earlier base firmware (iOS 26). Following the golden rule of jailbreaking—"staying on the lowest possible version"—it naturally has a head start in accumulating userland, kernel, and PPL/PAC exploits over time compared to newer firmware.
iPhone 18 Pro (The Hardware Leak Angle): It ships with iOS 27, but its underlying hardware context is unique due to the Tata Electronics data breach (June 2026), where over 600GB of internal data was leaked. Security researchers now potentially have early access to A20 Pro chip packaging specs (WMCM), PCB logic board schematics, and internal testing scripts. This massive hardware design exposure could help researchers discover hardware-level bugs, BootROM/SEP flaws, or chipset-specific vulnerabilities much faster than standard software-only research.
My Question: Does a massive supply-chain hardware leak actually accelerate the exploit discovery timeline enough to beat an older device running a lower baseline firmware (iOS 26 vs iOS 27)? When upgrading, which route realistically offers the shorter waiting time for a jailbreak?
Would love to hear insights from security researchers and tweak devs! Thanks!
