What you need
-
-
The new iPod touch 3rd Generation!
-
It's available in three different configurations, with both the 32 GB and 64 GB sporting a faster processor and OpenGL ES 2.0 support.
-
We don't think anything changed on the 8 GB touch. The only thing we know for sure has changed is the price (it's now $199).
-
According to Phil Schiller, "$199 is the magic price point in the iPod world." However, it sure seems people don't mind paying more. Apple's already sold 20 million iPod touches, all for more than $199 each.
-
-
-
We have a 32 GB touch. It looks identical on the outside, but does sport a new model number on the back, A1318. (The second gen touch was A1288).
-
The iPod touch didn't get nearly as much love as its smaller sibling, the new nano. There's still no camera.
-
For now anyway, if you want both a touch screen and a camera, an iPhone's your only option.
-
-
-
We're working on getting it open. In the meantime, let's have some fun with numbers.
-
Retailing for $399 in the US, you'll be paying $6.23 per gigabyte for the 64 GB touch. That's no match for the $1.56 per gigabyte for the 160 GB iPod Classic.
-
Going back four years, the original nano was $62.25 per gigabyte, while the hard drive-based 60 GB iPod Video of that era was $6.65 per gigabyte.
-
Interestingly, that means that today flash is roughly equivalent to where hard drives were four years ago. In 2005, you could purchase a 60 GB iPod Video for $399, while today you can get a 64 GB iPod Touch for the same price.
You sell selected nylon 'spudger' tools by Menda, which are great, but who's the OEM for the iPod opening tools?
Quote from jjb:
Did you find any indication on possible of adding GPS to ipod touch?
Unless there's a dedicated GPS receiver chip in there (which I don't see), the answer is currently no until apple makes the Bluetooth serial profile available (so standalone units could be used) or someone finally ships a receiver that connects to the accessory port. Same for a compass/magnetometer.

can you give more info on this?
what do you mean by "or someone finally ships a receiver that connects to the accessory port" ?

According to Apple, the new touch is up to 50% faster. It will be interesting to see how performance stacks up against the iPhone 3GS.
-
Getting this iPod open wasn't easy. Yes, we keep saying that about iPods lately. Unfortunately, there's not a single currently shipping iPod that isn't very difficult to open.
-
The front glass and digitizer isn't the same as on earlier touches. This is our most popular repair part on the iPod touch. We have these for both the 1st and 2nd generation, and will be adding parts for this one as soon as possible.
I was able to use this teardown to guide me in replacing the front glass and digitizer on a 32gb iPod touch 3rd gen. It is still extremely difficult to get the plastic frame from around the glass off, but after the use of a heat gun and some patience, I was able to do it.
Thanks a ton to Walter Galan for creating this teardown, I love what you do and look forward to more!

Tool used on this step:Phillips #00 Screwdriver$5.49
-
You get a free mirror with every iPod touch!
-
A Phillips #00 screwdriver makes quick work of the screws holding the LCD assembly in the touch.
-
The LCD is very similar, but not identical to that of the 2nd gen touch. The connector on this display is just a tad wider.
Quote from TuxRug:
I second that question. Why is there a "mirror" that you can't see unless you open the iPod? Does it serve as shielding or something?
I posted this on the iPod Touch 2nd generation repair guide, hope it helps:
I'm fairly confident that the mylar is there for viewing the display in direct sunlight and for reflecting the backlight/incoming sunlight back out through the LCD. If you hold the display assembly (without mylar) in front of a very intense light source, you'll notice it is a bit transparent and that light transmits through both the LCD and the backlight. Now, if you check out the metal tray that the LCD sits in, you'll notice that it is not a uniform flat surface due to many voids for screw holes, etc. If you were to view the display in direct sunlight without the mylar in place, you'd probably see all the voids in the metal display tray as unwanted "shadows" in your display. I'd install the mylar with the shiny side facing toward the outer glass, as oriented in our repair guide.

It's out!

You can see the speaker sitting on top of the logic board.
Quote from MD5Hash:
So is the speaker in the 3G touch much higher quality than the one in the 2G? I have a 1G, and have always been jealous on principle, but after hearing the actual audio output from the 2G speaker, I was kind of nauseated.
I Have a 2G and the sound does suck, at the apple store, i played with a 3G For a while, and it was a little better, also, a little louder. but i didn't have my 2g to compare it.

The battery. It's 2.92 Whr, which comes out to be 789 mAh.
Quote from baq:
Wait. How is 1080mAh at 3.7v come out to be 2.92Whr ? Wouldn't that be 1.08*3.7=3.996Whr?
I think you hit the "2" key instead of "3" while calculating this, because 2.92 Whr / 2.7 V is 1.08 mAh, but as the battery is 3.7v, not 2.7v what you should have gotten is 790mAh
You're right, I fixed my math. Thanks for pointing that out, and even figuring out what I did wrong.

After peeling away the speaker, here's the brains of the Touch.
-
Samsung looks to be the big winner here.
-
The primary ARM processor is adorned with the following:
-
339S0075 ARM
-
K4X2G303PE-SGC8
-
YNE069AC 0928
-
APL2298
-
Is this a new, faster processor? The processor on the last iPod touch (2nd gen) was labelled 339S0048ARM. The processor in the iPhone 3GS is marked 339S0073ARM.
-
-
-
The Samsung branded NAND flash.
-
There are two 128 gigabit packages, for a total of 256 gigabits. Divide that by eight, and that's 32 gigabytes of MLC NAND flash.
-
-
-
Broadcom BCM4329FKUBG wireless chip.
-
According to Broadcom, the BCM4329 supports 802.11n!
-
This is a big deal, as even the iPhone 3GS doesn't support 802.11n. The iPhone 3GS has a BCM4325 wireless chip, which only supports 802.11 a/b/g. We don't know yet if 802.11n will be supported in software, but at least the hardware's there.
-
There's also Bluetooth 2.1 + EDR and a FM receiver and transmitter packed into this chip. If they built in the antennas, and if Apple adds software support, you could theoretically stream music to your car stereo without any external hardware. But that's a lot of ifs.
I want an FM transmitter in my iPhone 3GS! That would rock...and roll?
Quote from brady:

So the chip supports it. Is there an FM antenna path and swtich? The spec shows FM doesn't share the Bluetooth and WLAN RF path, namely because they operate in different frequency bands. If the RF path isn't there, it doesn't matter whether you enable the feature in software or not.
Was the broadcom chip's die damaged during the ipod's disassemble? Or it is like this (have something like an "hoke" in the right botton side of the die)?
If they have the 4329 in them then why don't the devices support the 5GHz radio band? The 5GHz band allows wide channels which would double the throughput and probably save battery life when using Wi-Fi so why aren't the idiots at Apple using that band? The only way to get that 50Mbps of actual throughput on a single stream 802.11n device is on a wide channel in the 5GHz band. Apple has always been so forward thinking in terms of Wi-Fi, why are they crippling this device? Is it because they were unwilling to change the industrial design in order to fit a dual-band antenna into it? If so, that's just plain stupid.
Quote from Francy:

Reading the product brief, there are at least two versions of the BCM4329: the BCM4329H with 5GHz and 802.11a, and the BCM4329G without 802.11a and 5GHz. If you had a full datasheet, you could decode the entire part number, but I'm guessing the touch uses the BCM4329H.
Quote from Phishy:
Does the 8 GB touch include the 802.11n chip, or just the 32 and 64 GB models?
I want to know this also because i would want to sell my 8gb touch and get the new 8gb touch if it has that stuff on it. Please let me know asap...
Mi ipod touch 3g has been getting hot from the antenna, won't start up

It appears that Apple left in room for a camera in the top of the device. There is a 6mm Ă— 6mm Ă— 3mm space between the Broadcom chip and the wireless antenna. There isn't enough depth for an iPhone-style autofocus still camera, but just enough room for the camera that Apple used in the 5th generation iPod nano.
I'm pretty sure apple put the video camera on the nano to help sell more nanos, and didn't put it on the iTouch so that people would have to buy the iPhone instead. It make sense if you think about it: before, nanos and touches didn't even compare. Putting a video camera on the nano makes it unique, and a lot of people will buy it for that reason. The iTouch pretty much sells itself, so they don't really need to upgrade it that much. They'd rather you buy the iPhone which would make them more money. That's my take on it anyway. Looks like I'll sit tight until the next iTouch is announced.
Is the wireless antenna the little guy being held by the finger and thumb in this picture? Does bluetooth and wifi use the same antenna?
I have an iPod Touch 3rd Gen and I was wondering: If I bought an iPod Nano, could I put the Nano's camera in my Touch, or is there not a connector for it?

Other side of the board.

Not enough hardware for you? Just yesterday, we did a teardown of the 5th generation iPod nano.

Shameless plug: We sell hundreds of iPod parts for repairing your iPod touch, replacing an aging iPod battery, or fixing a cracked screen.
Quote from nofunsir:
In your teardown, have you guys seen any place where a camera would connect to the logic board?
A camera could connect using as few as 4 pins (ie, USB). With that in mind, two things pop out: the 6-pin device to the left of the camera space (is it a connector?), or the 5 solder pads below it around the hole (do they already connect something?).

Most imager ICs use 8-10 lines for output data, 3 lines for output-synchronizing clocks (frame, row, & pixel), one line for the master input clock, two lines for an I2C command-control interface, two supply lines (one for the digital I/O voltage reference, another for the analog reference), and ground -- call it 20 lines. The Nano's imager connector matches that perfectly.
had enough of ipod touch hardware

Well, I took mine apart and at some point it stopped working. If you're careful it will probably still work if you put it back together (mine was more like an autopsy because the touchscreen already didn't respond to input. I was then dumb enough to short the battery hoping the voltage drop would reset it, but now I probably also killed the battery. It could theoretically still be made usable with quite a bit of effort, but it wasn't even that great when it was new.
if my screen starts glitching out like as if the wire is loose is there a way to fix it my self
it's fine now but soon it'll start up again so is there a way to fix it my self like what materials would i need to set it back
My iPod screen replacement didn't come with the mirror that is supposed to be attached to the back of the screen upon replacement for the new one
Where is the hard disk??
Therre is no such thing here as hard disk.
It is NAND memory, mentioned in step 11
