There's tons of chips on the front of the board. Other chips of interest include:

Texas Instruments WL1271 chip that supports WiFi (802.11 b/g/n), Bluetooth 2.1, FM and GPS technologies (thanks Chipworks!)

Kionix KXTF9 accelerometer

ST Micro AGD8 2040 S6NBF gyroscope

Avago ACPM-7868 quad-band power amplifier

What's this? Did we use Content Aware to remove all of the chips from the back of the motherboard? The answer is no; there just isn't much going on with the backside of the board.

We find a microphone (red), proximity sensor (orange), ambient light sensor (yellow) on the back.
