Be sure to slide the metal spudger between the dock connector and the antenna cover, and not into the dock connector itself.
Insert a metal spudger into the slot between the dock connector and the antenna cover. Gently pry up near the two tabs to create a small gap between the antenna cover and the silver front bezel.
Insert an iPod opening tool in the gap between the antenna cover and the front bezel. The wedge of the tool should be pointing towards the antenna cover. Slide the tool around the corner and up until you reach the metal backing.
Repeat the same procedure on the other side of the dock connector.
Pry up the rear panel by pulling the dental pick clockwise in a quick motion. Apply force perpendicular to the plane of the display assembly. You may be afraid to go fast, but going slowly is more likely to bend the case.
The rear panel is still attached to the iPhone by the headphone jack cable, so don't entirely remove the rear panel from the iPhone just yet.
Working from the edge opposite the battery connectors, insert a spudger between the battery and the plastic frame and pry up on the battery. It is attached to the casing with an adhesive, but should slowly come free.
Leave the battery resting slightly out of its housing, but be sure not to put too much pressure on the battery wires as the solder joints break easily.
Continue to separate the two boards. The silver metal shielding may not immediately separate. If necessary, work around the edge of the board to separate the metal shielding.
If you are replacing the communications board, you need to desolder it from the battery. The battery replacement guide can help you remove the battery.
