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.

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 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.
