Architecturally, nearly all of the handset’s components have reportedly been relocated to the front side of the main logic board, including the Bluetooth, Wi-Fi, and Flash memory chips. The battery is identified as a 4.51 Watt-hours, or 1219 mAh, which is about 6% larger than the iPhone 3G’s battery. Also discovered was an additional antenna connection near the dock connector, though its function remains unclear.
