Back Cover Identication
The back cover of iPhone 4 includes glass that is very similar to the front cover glass. It is
possible to crack the back cover glass. A damaged back cover should be replaced if this occurs.
• Refer to the Visual Mechanical Inspection guidelines to determine warranty coverage for
cracked glass.
• Ax packing tape to damaged back cover glass before removal to prevent injury and
scattering of broken glass.
Regulatory Markings
Important: The back cover includes regulatory compliance markings and text. The replacement
back cover must be matched with the original, damaged back cover to comply with legal
requirements. See next page to determine the correct part number.
Replace the back cover only on devices that were purchased in the same country in which
service is being performed. Back covers are region- and country-specic in most cases.
If the regulatory markings and/or text are illegible, access regulatory information on iPhone:
Settings > General > About > Regulatory.
