Device-Specific Jailbreaking
Does Chipset Matter?
Yes, enormously. The processor (Chip) inside your iPhone determines which hardware exploits are available. For example, the checkm8 exploit only works on A11 chips (iPhone X) and older, making them jailbreakable on essentially any version.
Modern Devices (A12+)
For newer devices like the iPhone XS, iPhone 11 and newer (A12+), jailbreaks rely on software exploits which are patched frequently by Apple. This is why you must stay on older iOS versions to jailbreak modern devices.
