- P2 Pentalobe Screwdriver iPhone (if iPhone has external pentalobe screws)
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.
Pinch the rear panel with your fingers and lift it away from the iPhone. Alternatively, use a Small Suction Cup .
Remove the single 2.5 mm Phillips screw securing the battery connector to the logic board.
Use a plastic opening tool to gently pry the battery connector up from its socket on the logic board.
Remove the metal clip covering the antenna connector.
