The second type of unlock, often confused with the first, is the network “hack” or software unlock. In the early days of the iPhone (models up to the iPhone 4), baseband exploits sometimes allowed software unlocks via tools like ultrasn0w. These tools modified the iPhone’s baseband firmware (the chip that manages cellular communication) to accept any SIM. However, starting with the iPhone 4s and continuing through the iPhone 7 Plus, Apple dramatically hardened the baseband security. The iPhone 7 Plus, equipped with either the Qualcomm MDM9645M or Intel XMM7360 baseband chips, has never seen a public, reliable software unlock. The baseband is cryptographically signed and isolated; flashing a custom IPSW has no effect on it.
