Removing the single screw securing the dock connector cable to the rear case.

Notably lacking from this RF/data cable is anything GPS related. Check out the FCC iPad teardown to see where the GPS will be in the 3G device.

The 802.11n WiFi/Bluetooth card is integrated into the dock connector cable.

Hiding under the case:

• Broadcom BCM4329XKUBG 802.11n WiFi + Bluetooth 2.1 + EDR and FM

Dont worry, the capacitor near the lower right corner of the Broadcom chip didn't come that way. The solder melted and it moved when we heated the steel casing to remove it.

The speaker assembly is larger than we expected:

• The connector found on the speakers and other components is typical of the connectors seen in MacBook Unibody laptops. Translation: the iPad isn't that cramped for space.

Dual speakers provide mono sound. Two small sealed channels direct sound toward three audio ports carved into the bottom edge of the iPad. The audio-out jack provides stereo sound, of course.

That's a hulk of a battery: it weighs 148g with the casing.

Confirming our suspicions from yesterday, the battery integrates two separate 3.75V lithium polymer cells wired in parallel for such ample battery life.

Battery cell markings:

• P11GA6-01-C01F
• 741-00310A +

The iPad battery is a lot bigger than an iPhone 3G battery. The iPhone battery has about 1/5th the capacity provided by the iPad battery.

The second shot shows the battery cover peeled back to expose the protection and connection circuitry for each Li-Poly battery.

The third shot shows the other side of the battery board, which is stamped with Compeq.

The bare rear case. The antenna behind the apple logo looks just like the antenna on the new iMacs.

A little prying with a metal spudger is required to separate the antenna from the rear case.

Tolerances look pretty tight in the antenna compartment. Check out that pocket just for the antenna to sit in.

Here's a detail shot of both WiFi antennas. The wireless reception should be decent with such dense antennas.

Adding 3G capability to a Wi-Fi only iPad is not going to be a very feasible upgrade. Based on the photos released by the FCC, the 3G models include additional antennas as well as a plastic strip in the rear panel to improve reception.

Remove a couple screws and pull the headphone jack out of the rear case.

As with most portable devices, the headphone jack is very well fastened to the case.

The microphone's right next to the headphone jack and goes through the same data cable as the headphone jack.

Like the iPhone, it appears that the iPad features a liquid sensor in its headphone jack. If you get your iPad wet, don't expect Apple to fix it under warranty for you.
