One of the problems that sometimes occur with the iPhone 4 is that the screen can become damaged or cracked. Many people mishandle or drop their iPhone 4s every now and then which may not cause a problem. But, because the iPhone 4 is so expensive, dropping it may lead to some very expensive repairs. You can save a lot of time and money by taking your iPhone apart and replacing the screen yourself.

Remove the SIM card for your iPhone 4. First, find the small hole that is located on the top of the iPhone 4. Push a paper clip or pin down inside the hole to release the SIM card. If you push the button in far enough the SIM card will come out of the top of the iPhone 4.

Turn the iPhone 4 over to expose the back of it and remove the black cover. You may need to wedge a flat thin edge such as a razor or a butter knife between the two back covers if it does not slide off easily. Unscrew the 3 screws from the top edge that was covered by the back piece.

Remove the back silver case of the iPhone 4 by running a razor or butter knife along the whole back border of the iPhone 4. Carefully lift it up to expose the internal parts of the iPhone 4. There will be a film like gold ribbon that is attached to the back case that must be released prior to the back being able to be removed completely. Where the ribbon was connected to the iPhone 4′s body there will be a small plastic tab that you will have to lift up on in order to release it.

Find the silver antenna cable the runs along the right side of the iPhone 4. This cable will have 3 small circular pegs that you will have to lift up on to release this cable. The 3 circular pegs will be found at the bottom, middle, and top of the iPhone 4. Find and remove the ten small screws on the outside edge of the iPhone 4.

Find the silver parts that are on the inside of the iPhone4. There will be two primary sections inside the iPhone 4 and one will be silver and the other one will be yellow. Take out the 3 screws from the silver section that holds down the iPhone 4′s motherboard. Lift up on the whole metal silver piece to take the motherboard out. You will have to release 4 wires that are connected to the motherboard. Release the small plastic tabs to free the wires. Take the motherboard out and set it aside. The battery will also lift free since it is connected to the motherboard.

Remove the front piece of the iPhone 4′s external case. This piece should already be loose since you have already removed the screws. Find the 3 clips on either side of the LCD screen and hold the screen in place. Lift up and release these clips to remove the LCD screen. Be very careful with the screen since all of the wires that you have released during these steps are attached to it and 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 from exactly where you removed them.
