Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can

catch fire and/or explode if accidentally punctured.

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.
