This Apple Technician Guide provides troubleshooting steps, take apart procedures and other information about iPhone 4 and iPhone 4S. It is designed to be used in conjunction with the iPhone Visual Mechanical Inspection guidelines (070-2515).
This is a very handy document to have if you ever need to perform a repair or troubleshoot an issue with your iPhone. You might want to download it before it disappears.
In addition, Dickson has posted an AppleCare Service Training Doc for the MacBook Pro (Retina, Mid 2012) and MacBook Pro (Retina, 15-inch, Early 2013). Check that out below or download it.
