The battery. It's 2.92 Whr, which comes out to be 789 mAh.

We appreciate it when Apple prints the watt-hour ratings on their batteries, it makes our job a lot easier.

After peeling away the speaker, here's the brains of the Touch.

Samsung looks to be the big winner here.

The primary ARM processor is adorned with the following:

• 339S0075 ARM
• K4X2G303PE-SGC8
• YNE069AC 0928
• APL2298

Is this a new, faster processor? The processor on the last iPod touch (2nd gen) was labelled 339S0048ARM. The processor in the iPhone 3GS is marked 339S0073ARM.

The Samsung branded NAND flash.

There are two 128 gigabit packages, for a total of 256 gigabits. Divide that by eight, and that's 32 gigabytes of MLC NAND flash.

The chips looked like that when we removed the speaker, we didn't damage them ourselves. We're not sure if that's just adhesive, or if the packages were actually slightly melted.

The other side of the board.

You can see where the contacts for the battery connect to the logic board, just to the left of the word "APPLE."

An 8 GB 2nd gen touch logic board (left) and. our new 32 GB 3rd gen touch logic board.

Both machines have the same basic board design. However, on the 3rd gen, the NAND flash is split between two chips, leaving very little free space on the board.

Broadcom BCM4329FKUBG wireless chip.

According to Broadcom, the BCM4329 supports 802.11n!

This is a big deal, as even the iPhone 3GS doesn't support 802.11n. The iPhone 3GS has a BCM4325 wireless chip, which only supports 802.11 a/b/g. We don't know yet if 802.11n will be supported in software, but at least the hardware's there.

There's also Bluetooth 2.1 + EDR and a FM receiver and transmitter packed into this chip. If they built in the antennas, and if Apple adds software support, you could theoretically stream music to your car stereo without any external hardware. But that's a lot of ifs.

It appears that Apple left in room for a camera in the top of the device. There is a 6mm x 6mm x 3mm space between the Broadcom chip and the wireless antenna. There isn't enough depth for an iPhone-style autofocus still camera, but just enough room for the camera that Apple used in the 5th generation iPod nano.

Other side of the board.

Not enough hardware for you? Just yesterday, we did a teardown of the 5th generation iPod nano.

Shameless plug: We sell hundreds of iPod parts for repairing your iPod touch, replacing an aging iPod battery, or fixing a cracked screen.
