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.
