Unboxing

We won’t bore you with a lengthly unboxing, since there’s nothing new to see here.

Twins

Which one’s the 3G S? They look identical.

Model number

Apple doesn’t make it easy to identify your iPhone 3G S, as they’re all labeled just “iPhone.” However, the 3G is model A1241, while the 3G S is model A1303.

Get the screw driver

The original iPhone was very difficult to open, but we expect the 3G S (like the 3G) to be quite serviceable. There are still two visible screws on the bottom of the phone, which is a good sign for easy opening. Remove the two bottom screws with a Phillips #00 screwdriver.

Suction

A small suction cup is your friend. A large suction cup may also be a fun toy. There are seven numbered connectors on the 3G S, up from six on the 3G. Connector number seven is in the lower right corner, just above the dock connector.

The seven

There are seven numbered connectors on the 3G S, up from six on the 3G. Connector number seven is in the lower right corner, just above the dock connector.

Disconnect

There are three cables holding the LCD and digitizer to the rest of the logic board. Disconnecting them is as easy as 1-2-3.n

Camera comparison 1

We’re looking forward to the improved 3 megapixel camera on the 3G S. According to our good friend Richard Lai, “Camera quality is much improved from the 3G one, close up shots were possible down to about 5cm, brightness adjusts well when picking focus area.” We’ve seen some pretty impressive shots already.

nFortunately, as in both the original and 3G iPhones, the camera’s a separate component, so removal is possible if necessary for security purposes.

Two halves

Here’s the two halves. All the chips on the logic board are hidden beneath two large EMI shields. We’ll have those removed in just a bit.

LCD

Just like the iPhone 3G, the LCD is pretty easy to replace. After removing 7 screws, the LCD simply lifts out.

Digitizer

On the iPhone 3G, we see a lot more cracked digitizers than cracked LCDs. Replacing the digitizer is a little more work, and requires breaking out a heat gun or hair dryer.

Do not remove

Here’s the fabled “Do not remove” sticker. It didn’t stop us last year, and it’s certainly not going to stop us this year.

Single PCB

Removing the logic board. Like the 3G, there is a single large PCB with all components.

Main circuit board

The main logic board. There’s a lot packed in here.

nThe Apple-logo chip is the primary Samsung ARM processor.

nThe 16 gigabytes of Toshiba flash are now on the front of the board, just below the Samsung ARM.

Back of main PCB

The other side of the logic board. You can see the battery contact pads in the lower right corner. Apple was again kind enough to not solder the battery to the logic board.

Battery life

Apple promises improved battery life with the 3G S. The battery is listed as 3.7V and 4.51 Whr. This comes out to 1219 mAh, compared to 1150 mAh on the 3G. That’s only a 6% increase.

Video recording

Video recording is a long-overdue feature of the iPhone 3G S. The 3G S records video at 640×480 resolution and 30 fps.nThe video recording quality appears acceptable, although not exceptional.

Needs work

According to Richard Lei, the “Chinese (Cantonese) voice control works, but took a while to work out the magic words as there is no guide released yet (not out in Hong Kong until early July)”

All taken a part

Here’s all the parts. We’ll continue perform further analysis, so check back for updates
