1- Three 1.8 mm Phillips #00 screws securing the headphone jack and GPS antenna to the rear panel.
One 3.8 mm Phillips #00 screw in the plastic loop near the headphone jack.
2- Remove the four Phillips #00 screws securing the volume and vibrate buttons.
The screw on the far right is slightly longer than the other 3 screws. When reassembling the phone, keep this in mind.
3- Lift the volume button circuitry away from the side of the iPhone, and carefully peel up the orange ribbon cable from the rear panel.
4- Carefully lift the headphone jack assembly out of the iPhone.
Switch the green mute switch down (towards the back side of the iPhone) into mute position. This will make it much easier to insert it, once the new mute button is in place.
5- Lift the vibrate button out of the iPhone
