Circuit schematic of the Apple iPhone 4 in PDF format, 2.31 MB. Only the model is given in the name, with no logic board number or revision, so match the document to your board before relying on it. Useful for no-power, no-charge and no-backlight faults, it shows rail names, connector pinouts and the path of signals between chips, allowing targeted voltage and diode-mode measurements. Any PDF reader can open it, and a matching boardview helps locate the parts it references.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardview. Enginerys does not host this file.
