iPhone 3GS

Revamped version of the iPhone 3G with faster

processing speeds. Repair of this device is similar to

the 3G, and requires simple screwdrivers and prying

tools. Model A1303 / 16 or 32 GB capacity / black or

white plastic back.

To get all the latest updates as we're doing the teardown, follow us on twitter! We also

have some video clips uploaded through the iPhone 3GS courtesy of our fellow friend

Richard Lai; he's created a playlistfor all to enjoy. Many thanks to our friends at MacWorld

UK, who let us use their office and equipment for the teardown.

We have the iPhone in hand!

We didn't have to travel quite as faras last year toget it. This year, it was only 5,400 miles away.

We lost the corporate jet due to the economic

downturn. Our CEO had to settle for an Italian bi-

plane. 47 hours later he was in London.

Apple claimsthe iPhone 3GS is "up to 2x faster."

Why is the 3GS faster? We'll find out soon enough.

According to rumors, the 3GS has a 600 MHz

processor, 50% faster than the processor in the

iPhone 3G.

We won't bore you with a lengthly unboxing, since

there's nothing new to see here.

Which one's the 3GS? They look identical.

Apple doesn't make it easy to identify your iPhone

3GS, as they're all labeled just "iPhone." However,

the 3G is model A1241, while the 3GS is model

A1303.

The original iPhone was very difficult to open, but

we expect the 3GS (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.

1 A small suction cupis your friend. A large suction

cupmay also be a fun toy.

There are seven numbered connectors on the 3GS,

up from six on the 3G. Connector number seven is

in the lower right corner, just above the dock

connector.

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.

1: LCD panel

2: Digitizer

3: Ear speaker

We're looking forward to the improved 3

megapixel camera on the 3GS. 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

prettyimpressiveshotsalready.

Fortunately, as in both the originaland 3GiPhones,

the camera's a separate component, so removal is

possible if necessary for security purposes.

In each image, the left photo is from the iPhone

3G, the right photo is from the iPhone 3GS.

For those who reallywant to examine the pictures:

hi-res1, hi-res2, and hi-res3.

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.

Just like the iPhone 3G, the LCD is pretty easy to

replace. After removing 6 screws, the LCD simply

lifts out.

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.

7 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.

Removing the logic board. Like the 3G, there is a

single large PCB with all components.

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

Here's a high-resimage of this shot.

The Apple-logo chip is the primary Samsung ARM

processor.

The 16 GB of Toshiba flash are now on the front of

the board, just below the Samsung ARM.

phoneWreck sent us a great component diagram

(second picture). They performed a thorough chip

analysisof the iPhone 3GS, so check out their site!

1 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.

Here's a high-resimage of this shot.

1 Apple promises improved battery life with the 3GS.

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.

8 Video recording is a long-overdue feature of the

iPhone 3GS. The 3GS records video at 640x480resolution and 30 fps.

The video recording quality appears acceptable,

although not exceptional. You can see a video

(taken using another iPhone 3GS) of us opening

the phone.

The 3GS offers Voice Control. We're not sure yet

why this feature couldn't be added via software to

earlier iPhones. Perhaps the voice recognition

requires a better microphone than in earlier

iPhones or a lot of processing power, or maybe

Apple just wanted to differentiate the 3GS.

According to Richard Lai, 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)." He also

tested the "Chinese (Mandarin) and Chinese

(Taiwanese), although the latter didn't work as wellsince [he doesn't] do the accent well."

you can get a 32gb 3gs from at&t for 500 bucks without a contract. then unlock it yourself. 800 bucks is way too much.

Im new here on this forum, im from Germany so please excuse my bad eng ;(

Well, I bought an Iphone 3 G[S]from Ebay.Uk, for about 700 Euros. (in Europe Iphone is very epxensiv). So my probles is that it

sometimes Crush without an reasen (but often after unlock with Ultrasn0w)and doesnt turn on again (display just keeps black)if i

do it on my power adapter then it turns on again but when im putting the plug out display is getting black again. Now after many

houers/day just spending on restoring i have recogniced that its an hardware defect because if i press 1 cm about the I from the

Iphone letters it goes on but then stuck on restart. So i wanted to ask what hardware part is behind the letter I and above i would

try to rapair it.

Have a nice Day.

i need to remove the bezel

austin,January 15, 2010

Does anyone know what that little metal stub in the very upper right hand corner of Step 11 picture does? Is it only meant to tuck

behind the bezel to keep the motherboard down during assembly or does it have any function electronically? Mine fell of and I

reattached it with a drop of solder underneath and now my PC doesn't recognize my phone. Not sure if it's something else or not.

Dmitry,January 23, 2010

I believe the antena is at the top left by the headphone jack. But I could be wrong

austin,January 28, 2010

The Nor chip is listed as (Infineon-36MY1EE) all over the web but i am confused with INTEL it has the i sign on it which INTEL has on

it please someone give details about it. Its INFINEON OR INTEL?

Quote from blufire:

Sony's DSCs have had that feature for a while now (at least half a year?)

Ah, I missed that. Thanks! You know the model?

Still, I'm wondering how that feature is being crammed into a max 0.4" module height. Surely, there'd be other phones with the

same capability. 1/4" 3mp is pretty old hat. EETimes says it's a 3mp OmniVision autofocus module, but that could mean any

number of chips including the TrueFocus one.

It just seems that if the DigiTimes rumor is fully true (which 1/2 seems to be), that Apple will be using OmniVision's 5mp TrueFocus

also since that's the only one available for the 1/4" form factor (would they really use 1/3"? can it fit?), I'm wondering why they

wouldn't use the 3mp version of TrueFocus, too.

PS It looks like there's no curvilinear distortion in the iPhone's pics. Am I just seeing things?

is from OmniVision? there are a OV630 image processor?

http://www.ovt.com/products/truefocus.ph...

Well, EETimes says it's an OmniVision 3mp autofocus.

http://www.eetimes.com/news/semi/showArt...

This really doesn't help much, considering the wide variety of abilities inherent in a Wavefront Coded system such as the

TrueFocus product line (1/4" 3mp and 1/4" 5mp) and the wide variety of 1/4" 3mps that OmniVision offers. I still can't find a

cameraphone-class module that focuses in the way that iPhone does (into and out of macro mode seamlessly), so TrueFocus

seems the most logical explanation. Also, this may be poor estimation on my part, but it looks like the iPhone 3gs has no

curvilinear distortion, implying TrueFocus again.

http://www.freepatentsonline.com/y2006/0...

PS The 2-chip TrueFocus solution is all but dead. It looks like the 5mp TrueFocus may be adopted by some unnamed future Apple

device and Storm 2. Who knows?

Any sign on the circuit boards of the hypothetical DSP that has been proposed as required for the voice control feature?

The ARM chip is based on the the Cortex-A8, which includes a powerful DSP called NEON as a built in part of the A8 chip

architecture. It doesn't need an external DSP. The A8 and NEON were announced several years ago, you can google more info.

NEON is not a DSP. It's more accurate to describe NEON as a set of SIMD instructions, implemented in a separate but tightly-

coupled section of the processor.

I read in another forum that voice control is something quite processor-heavy, so maybe they needed the 600Mhz-piece to pull it

off acceptably...

...but that's only what I've read, I have no idea...

Xav0r,June 29, 2009

what is this part? it appears that i have severed a sodder and am wondering if i can find a replacement.

tim,January 14, 2010

Thanks for yet another great teardown :)

blufire,June 19, 2009

How easy is it after the breakdown you have already done to replace the rear black plastic case as I still see a lot inside this

Thanks

It shouldn't be too hard to replace the rear plastic case at this point. You can look at the iPhone 3G rear case replacementto get an

idea of what else needs to be done. However, the bigger problem is finding a rear case to replace yours with. We don't sell them

because we can't find any that meet our quality standard. Beware of retailers trying to sell rear panels for the 3G or 3GS "without

internal parts" -- those panels are a waste of money, as they will not mate properly with the front panel.

I would like to replace the chrome bezel on my iPhone 3G. Is it easy to detach the old bezel and reattach the new one to the real

panel, or is it glued to the frame?

jdesorme, August 16, 2009

Meh I would love to put a 3GS hardware inside a 1st gen aluminum case :D

HQuest, September 19, 2009

Is there any way to order the parts and build an iPhone or get a broken phone and replace most of the parts? If so, how would youget software on it? Would it be unlocked?
