Apple iPhone 3GS schematic, provided as an 8.92 MB PDF. The circuit drawings let repair staff follow the supply rails, check charging and backlight sections, and trace data lines between the processor, memory, baseband and connectors when diagnosing a no-power, no-image or no-service fault. Open it in any PDF viewer and use the search function to jump to net or reference designators. Since the 3G and 3GS look alike externally, verify the model before using this diagram, as the boards are not interchangeable.
