  • Apple iPad 3G: Main screen

    From the front, the Apple iPad 3G is nearly identical to the iPad Wi-Fi. The only visible difference is the black, plastic strip that runs along the devices top edge.

  • Apple iPad 3G: microSIM card

    The Apple iPad 3G uses a microSIM card. The card is significantly smaller than a traditional SIM, but the metal contacts are the same.

  • Apple iPad 3G: Right side

    As on the Apple iPad Wi-Fi, the right side of the iPad 3G contains the screen rotation lock switch and the volume up/down button.

  • Apple iPad 3G: Top

    Along the top of the Apple iPad 3G, you find a black, plastic strip, which extends down the back of the device. As noted earlier, this plastic strip conceals one of the iPad 3G's cellular antennas and the GPS antenna.

  • Apple iPad 3G: Removing the front glass panel

    I cracked open the Apple iPad 3G using the same techniques as I used on the original iPad Wi-Fi.

    I insert a thin metal blade between the metal case and the front panel assembly's black rubber gasket. Then, I slowing and gently worked my way around the left side of the case releasing and/or breaking the metal clips that hold the front panel to the metal case. Once enough of the clips where pried loose, I was able to lift the left side of the front panel away from the metal case.

    To completely separate the front panel from the metal case, you must disconnect four cables. The iPad Wi-Fi had three cables.

  • Apple iPad 3G: Inside

    With the two halves separated, we get our first good look at the hardware inside the Apple iPad 3G. I wasn't surprised to an internal layout nearly identical to the iPad Wi-Fi.

  • Apple iPad 3G: Metal case

    Within the Apple iPad 3G's metal shell, are the main logic board and 3G communications board (mostly covered by metal EMI shields), the batteries, Wi-Fi and Bluetooh card, antennas, headphone jack, microphone, speakers, On/Off button, volume up/down button, screen rotation lock switch, and microSIM card slot.

  • Apple iPad 3G: Metal case top

    At the top of the Apple iPad 3G's metal case, you can see the inside of the black plastic "RF window". Attached to this plastic strip are one of the cellular antennas and the GPS antenna.

  • Apple iPad 3G: Metal case bottom

    At the bottom of the Apple iPad 3G's metal case, we find one of the Wi-Fi antennas, the speaker assembly, data port, and the contacts for the home button. Along the left side, is the microSIM card slot. The black connector strip that runs down the center of the battery assembly, attaches the components at the bottom of the device to the main logic board. Under the connector, you also find the Wi-Fi and Bluetooth communication cards. A second antenna is mounted behind the battery assembly.

  • Apple iPad 3G: Front panel cables

    The front panel assembly has four cables. Starting with the round cable at the bottom left of this picture and working your way across the top and to the right, you'll find the display cable, an antenna cable new to the iPad 3G, the ambient light senor and cable, and on right side the ribbon cable for the digitizer.

  • Apple iPad 3G: CPU, RAM, and other chips

    With the EMI shield removed, we can see the core of the iPad 3G. As on the iPad Wi-Fi, we find the 1GHz Apple A4 processor, two Samsung NAND flash memory chips, the Broadcom I/O controller, and chips from Texas instruments and NXP.

  • Apple iPad 3G: Metal clips

    The Apple iPad 3G's front panel is held to the metal case with plastic tabs and several metal clips. As I did when disassembling the iPad Wi-Fi, I broke several of these clips when opening the iPad 3G.

  • Apple iPad 3G: Internal rubber cushions

    The two small rubber cushions help separate the front panel assembly from the metal case. They came off during this cracking open.
