The iPhone has two PCBs sandwiched together. As I wanted to reassemble the phone in working order, I decided against separating them. According to various Internet reports, the iPhone uses an ARM1176JZF-based processor manufactured by Samsung (S3C6400) that operates at 667MHz. According to the ARM website, the ARM1176JZ(F)-S chip uses ARM TrustZone technology to improve security, ARM Jazelle technology for embedded Java execution, and ARM Intelligent Energy Manager technology to reduce processor power consumption.
