Contents Now We have it in our hands, lets see whats in the box.
We decided to opt for the black 32GB. Out of the box it looks sleek, slim, & ready to multitask.

The iPhone 4 from the back. Note the improved rear camera with the LED flash. 5 Megapixel Video recording, HD (720p) up to 30 frames per second with audio. The back panel is again flat like the iPhone 2G. 3G & 3GS back panels are curved & wobble on a flat surface.
|
|
|
|
Step 1 The new iPhone 4 has two phillips screws on the bottom as did the iPhone 3G & 3GS. Unlike previous models, the back panel is removed first to expose the internals of the iPhone 4. |
|
|
Step 2 Now Slide the back panel upwards to expose the internals. |
||
|
Once the back panel has been removed, there are several steps involving screws & clips. The stainless steel case & bezel are a nice touch. Apple reduced the size of this new model substantially while improving antennae placement. |

Step 3
Once you get started, there's no turning back. Holy screws!!! Take a look at the figure to the left. The Red circles outline all of the screw locations available for now. Now Set aside the vibrator. In order to place the proper screws back later, print out the photo to the left, & set the screws on the location map. |
||
| After all the screws have been set aside, it is time to remove the metal shim. Carefully detach the dock cable with a Nylon case open tool. | ||
| The Circled is a picture of the dock cable clip removed. | ||
|
|
Now Remove the circled battery clip shim to expose the antenna.
Now Remove the mega juiced battery by lifting the plastic tab upwards. Make sure you have removed the screw holding the battery board connection (bottom left of battery). Do not tear anything, go slow.
This new style battery is solderless, and very easy to replace like the 3G & 3GS. Battery specs: Li-ion Polymer Battery ****************** 1420 mAh 7 hours of talk time on 3G or up to 14 hours on 2G. |
|
|
Step 4 Remove the dock speaker-wireless antennae module. |
||
|
|
Please Note the two liquid damage indicators, the bottom one has no screw underneath, the top one does. Remove that screw now. | |
| When most of the screws have been removed, lift the board shim out & set it aside. | ||
|
|
Step #5 Note the new screw & clip locations. The six green circles fasten the LED backlit screen. There are several clips to remove in this next step: board cable, digitizer, screen, etc.
|
|
|
|
Next Remove the rear facing camera, one clip holds it in place. What an improvement from older models. 5MP camera that shoots 720P video with audio at 30 FPS.
|
|
|
|
Step 6 Next After all the clips and screws have been removed, the board lifts pretty easily out. Removing the shielding is not recommended. We simply did this to identify the chips on the board. The Largest chip in red is the Samsung K9PFG08 flash memory module Directly left of the flash memory is the Cirrus Logic 338S0589 audio codec with the Apple stamp. The Digitizer touchscreen controller boxed in yellow.

Here is a Back side board shot detailing all of the board chips.

After all the device clips have been removed there are some trivial steps involved in getting the Digitizer/Screen combo out of the front.
6 larger screws with washers hold the screen module in place, remove them & carefully slip the screen cables through the hole in the bezel. iPhone 4 has a Screen/Digitizer combo. Similar to the first iPhone, iPhone 4's display module is one piece. We have to confirm this, but it may be possible to replace the digitizer & screen separately. |
|
|
|
Next Prior to removal of the LED backlit screen, there are several smaller components you may wish to remove. We won't go into detail on removal of the headphone jack or volume buttons. But They are very easy to remove. View the sleek new mid-frame bezel, it houses several components responsible for GPS, wireless, bluetooth, & more. The home button slides out through the front. Make sure the clip on the backside is lifted prior.
The front facing camera is very tiny. A metal plate with clips holds this in place. Also pictured is the dock port & mic combo.

Completed After a long wait, the iPhone 4 is finally torn apart. Many of the parts inside are replaced with little effort. |
