    • Power off your iPhone before beginning disassembly.

    • Your iPhone 4 rear cover may have either two #000 Phillips screws or Apple's 5-Point "Pentalobe" screws (second image). Check which screws you have, and ensure you also have the correct screwdriver in order to remove them.

    • Remove the two 3.6 mm Pentalobe or Phillips #000 screws next to the dock connector.

    • Be sure the driver is well seated when removing Pentalobe screws, they are very easy to strip.
