Step 2
To begin, a summary of essential procedures follows.
With dimensions of 4.5 inches by 2.4 inches by 0.5 inches, a single iPhone has a weight of 4.8 ounces, equivalent to 0.3 pounds; to provide scale, the mass of 18 iPhones matches that of a single MacBook Pro.
The screen measures 3.5 inches diagonally and offers a resolution of 480 by 320 pixels, totaling 153,600 pixels—a quantity representing 12% of the pixel count found in a 15-inch MacBook Pro.

Step 3
Proceed with caution; the next step requires careful manipulation to disengage the component, and the precise method is currently under evaluation.
The iPhone utilizes four distinct wireless communication methods.
The device supports GSM connectivity across four bands—850 MHz, 900 MHz, 1800 MHz, and 1900 MHz—along with 802.11b/g wireless networking, EDGE data transfer, and Bluetooth 2.0 + EDR functionality.

Step 4
No information is provided.
The iPhone incorporates H.264 video decoding, which is probably implemented using dedicated hardware.
A 2-megapixel camera is also included.
According to an exclusive interview with setteB.IT last March, the camera utilizes an MT9D112D00STC model, internally referred to as K15A or MI-SOC2020.

Step 6
Reattach the rear enclosure, ensuring proper alignment with the display assembly and frame.
To access the SIM card, insert a paperclip into the aperture located on the device's top surface; a greater-than-anticipated force may be required to eject the card.
To utilize a SIM card from a different carrier, the phone requires unlocking; otherwise, it is restricted to operation solely on AT&T's network. International use is presently limited to roaming charges associated with a US-based service plan.

Step 7
The device is now disassembled.Expect some difficulty completing this step.
Begin by detaching the black antenna plate.
Locate the grounding screw affixed to the rear panel; it secures the antenna cable and establishes an electrical connection between the front and back case sections.

Step 8
Carefully detach the front case from the rear case, ensuring no damage occurs to the retaining screws (M3 x 6mm) or surrounding components; use a Phillips #0 screwdriver as needed.
Before the rear panel can be detached, first disconnect the cable connected to the headphone jack.
Due to the headphone jack's inset position within the device housing, standard 1/8" headphone plugs typically require an adapter for compatibility.
To lessen stress on the small metal connector when headphones are pulled, Apple incorporated a design where the rigid plastic cable sheath bears the brunt of the force.
An integrated microphone is included in the headphone design; a press-and-hold action on the button activates call answering functionality.

Step 11
Carefully detach the two antenna cables.
To ensure a secure connection and prevent potential issues, a small amount of adhesive is applied beneath each antenna connector.
Given Apple's history, particularly lessons learned from the iPod era, exceptional attention to component durability and overall system dependability was clearly prioritized in the design and manufacturing of this device.

Step 14
Using a Phillips #00 screwdriver, detach the ten screws circling the device's edge.
Step 15
This battery is identified by Apple's model number L1S1376APPC, specifically 616-0290.
Step 16
Carefully raise the logic board to reveal three connectors located on its underside.
- Carefully handle the component, ensuring no damage occurs, and refer to the parts list for identification.
- Employ a capacitive sensing method to detect physical contact.
- Connect the display's data and power lines, ensuring proper alignment and secure fastening to the motherboard using the provided screws (M3 x 6mm) and observing polarity markings to prevent damage.
Step 17
Carefully detach the remaining electrical connector.
Step 18
To release the dock connector cable, lift the retaining bar.
Step 19
Carefully examine the logic board, noting its double-layered construction which can obscure visibility of individual components.
Due to the risk of logic board damage, disassembly of the two component sections is not feasible, preventing internal inspection.

Step 20
The device's internal components, specifically the logic board and battery, have been detached for clearer visibility.
Step 21
To access the dock connector, detach the antenna cable located on the left side.
Step 22
Carefully lift the antenna ribbon assembly away from the large black plastic component.
The iPhone’s rear casing features a black lower portion to accommodate the antenna, which spans the entirety of that area.
