Step 8

Step 8 image
This unit, identified as the black model, was acquired for $979 New Zealand dollars and is currently locked to the Vodafone network; while white variations may exist, they are exceptionally uncommon. Its intended use in California remains to be determined.
Recognize the components and materials by their appearance.
Initial data indicates these parameters:
At 4.5 inches by 2.4 inches by 0.48 inches—a difference of 0.02 inches in thickness compared to the initial iPhone model—the iPhone 3G has a mass of 4.7 ounces, which is 0.1 ounce lighter than its predecessor; this weight is roughly equivalent to that of two swallows that are not carrying any load.
Due to the redesigned, curved rear casing, the iPhone's dimensions are not straightforward to determine using traditional geometric formulas; therefore, avoid attempting to measure its volume by displacement.
This screen measures 3.5 inches diagonally and offers a resolution of 480 by 320 pixels, resulting in a pixel density of 163 pixels per inch; it's a component functionally equivalent to those found in iPhones.

As a reference point, you can find a detailed guide on how to take apart the previous iPhone model online.
  • We anticipate these outcomes.
  • The processor is a Samsung component branded by Apple.
  • The device must either include an Infineon GPS chip or lack GPS functionality entirely; if no discrete GPS chip is present, the GPS receiver may be integrated within the processor.
  • Many integrated circuits bear solely Apple's branding, necessitating disassembly to identify their function in most instances.
  • Carefully detach the display assembly by releasing the four 3.5mm Phillips screws securing it to the chassis, then gently slide the display upwards and away from the device, observing that it is connected with a flexible cable and should not be forced.

Step 12

Step 12 image
Pivot the screen upwards.
Connectors to the logic board are sequentially identified with orange adhesive labels, numbered 1 to 6 by Apple.
Because the camera's connection is situated on the logic board's lower edge, accessing it for removal will probably require logic board disassembly from the device. While we have not performed this camera removal procedure, we anticipate that, similar to the original iPhone 3G design, the camera can be detached, allowing for secure device placement in sensitive environments.
Following the United States product launch, TechOnline will be removing the ceramic coating from unidentified integrated circuits via an acid immersion process, enabling detailed internal analysis utilizing X-ray technology and specialized diagnostic tools.

Step 13

Step 13 image
The unit's display component has detached.
Unlike the original iPhone design, the iPhone 3G’s LCD and protective glass are now distinct parts, mirroring the iPod Touch construction. Previously, these components were bonded together, which substantially increased the cost of screen replacements. Given that the glass is the most frequently damaged part, this separation simplifies and reduces the expense of iPhone 3G repairs.

Step 14

Step 14 image
To detach the glass component from the LCD panel, use a Phillips #00 screwdriver to unscrew and remove all six screws.
During LCD panel removal, note that the glass component, which incorporates touch sensor technology and embedded chips, is located directly below.
Unlike earlier iPhone models where the display integrated numerous components, the current design features a display directly connected to the main board, simplifying the replacement process and addressing previous difficulties in sourcing reliable display components.

Step 15

Step 15 image
Carefully examine the internal components of the iPhone to locate the 3G circuitry.
The logic and communications boards have been integrated into a single, elongated component, extending along the device's full length instead of being stacked as in previous designs, likely to accommodate a larger battery.
The resulting images are exceptionally good, thanks to the invaluable assistance of our collaborators in New Zealand.
