[From Miro, iFixit] Kyle flew to London to take apart the new iPhone 3G S! He enlisted the help of MacWorld UK and some locals to make one of our best teardowns yet.
We managed to video the dismantling of an iPhone 3G S WITH another iPhone 3G S. The videos are linked off the teardown.
This teardown features our usual world-class photography and exclusive hardware analysis. We'll be adding more information over the next few days as we continue to research the hardware design.

Points of interest:
* Thankfully, opening the iPhone 3G S is as simple as the 3G. After removing two Phillips screws, the two halves of the phone are separated easily using a suction cup.
* The iPhone is differentiated externally only by a new model number, A1303. The lettering on the back is now shiny, like the Apple logo.
* The internal physical design is virtually identical to the iPhone 3G. A random passerby on the street would not know the difference. Heck, even we were struggling to differentiate the two.
* The new graphics core should drastically improve performance, meaning Apple's serious about the handheld gaming market.
* There's still a "Do not remove" sticker above the logic board. Naturally, we removed it.
* Nearly all components have been relocated to the front side of the main PCB, including the Bluetooth, Wi-Fi, and Flash memory chips.
* The battery is 4.51 Watt-hours, or 1219 mAh. That's about 6% larger than the iPhone 3G's battery. Hopefully the hardware runs more efficiently, since increased battery life will not come from the battery
itself.
* There is an additional antenna connection near the dock connector. We're not sure what for just yet. However, we do love exploring these teasers... Stay tuned!
* For those who are wondering about the fingerprint-resistant coating on their iPhone 3G S screen: The oleophobic, or oil-proof, technology evolved from waterproofing. Oil-proof technology is harder to achieve as oil has a much lower surface tension than water, so it spreads out easier and thus is harder to get rid off. MIT's solution was to create a coating material which creates a layer of micro fibers, but with a much
larger contact angle between the oil droplets and the fibers.
Some comments on usability of the 3G S:
* Camera quality is much improved from the 3G. Close-up shots were possible down to about 5 cm, and the brightness adjusted well when picking a focus area.
* The oleophobic screen does seem to clean slightly easier than the 3G's normal screen.
* Google Earth (duration of the spinning load wheel) (over Wi-Fi): 3G S: 4.9 sec; 3G: 22.2 sec. A bit faster than Apple's claim of 2X speed improvement -- although we know that one simple test of one application
means little in the real world.
