- 1). Remove the iPhone's sim card. To do this, locate the pin-sized hole on the top of the device. Push a pin or paper clip down inside the hole to release the sim card. When your push the button in far enough the sim card will pop out of the top of the iPhone.
- 2). Flip the iPhone over to expose the back of the device. Slide the black covering off of the device. If it does not slide off easily you may need to wedge a thin flat edge of something between the two back coverings to get it to slide free. Use a butter knife or razor if the covering will not slide off easily. Once the black cover is off the device, unscrew the three Phillip's head screws from the top edge that the black piece was covering.
- 3). Remove the back silver case of the iPhone by running the thin flat-edged object you used in Step 2 along the entire back border of the device. Once the back case iz loose, lift up carefully to expose the internal components of the iPhone. There will be a gold film-like ribbon that that attach to the back case that you will need to release before the back can be completely removed. Follow the bold ribbon to where it was connected to the iPhone's body, there will be a small plastic tab that you need to lift up on to release the ribbon. Once the ribbon is free, set aside the back case of the iPhone.
- 4). Locate the silver antenna cable the runs along the right side of the iPhone. This cable will be three small circular pegs that you need to lift up on to release this cable. These three circular pegs are located at the top, middle and bottom of the device, along its right side. Once the antenna cable is free, locate and remove the 10 small screws on the outside border of the iPhone.
- 5). Locate the silver components on the inside of the device. There will only be two main sections that you will see inside the iPhone; one is yellow, the other is silver. Remove the three screws from the silver section, which hold down the iPhone's motherboard. Lift up on the entrie metal silver piece to remove the motherboard. There will be four wires that connect to the motherboard that you will have to release. Just as you did in step 3, follow these wires to where they are held down and release the small plastic tabs to free the wires. Remove the motherboard and set it aside. The battery, which is the large yellow section you see, will also lift free as it is connected to the motherboard.
- 6). Remove the front piece of the iPhone's external case. Because you have already removed the bordering screws in step 4, this piece will already be loose. Once the front case is removed, locate the three clips on either side of the LCD screen and hold the screen in place. Lift up and release these clips to remove remove the LCD screen. Be extremely careful with the screen because all of the wires that you have released during these steps are attached to the screen so they will come with the screen when you remove it. Clip the new screen in and reassemble the iPhone by attaching all of the components back exactly where you removed them.
