Second iPhone 3GS teardown

Little has changed in the layout of the iPhone 3G S, a second teardown reveals. Going beyond the included chips and manufacturers, iFixit notes that the arrangement of parts in the 3G S is "virtually identical" to that of the iPhone 3G, to the extent that even experienced technicians may have trouble distinguishing designs. The most significant change is said to be the rearrangement of components to the front side of the PCB, including chips for Wi-Fi, Bluetooth and flash storage.

An extra antenna connection is said to be present near the dock connector, though for what reason is uncertain. The battery is meanwhile rated at 1219mAh, or 4.51Wh. Although 6 percent larger than the one in the 3G, it is thought that the new battery cannot be the source of the 3G S' longevity. Apple may instead be using more efficient chips and circuitry, iFixit comments.
