iPod Touch 4th Generation Teardown

Teardown
Teardowns provide a look inside a device and should not be used as disassembly instructions.
Featured Guide
This guide has been found to be exceptionally cool by the iFixit staff.
We are ecstatic to finally have the opportunity to disassemble an iPod Touch with a camera and not just an empty camera slot.
This is one of three iPod teardowns this week! We also took apart the new iPod Nano and Shuffle. Stay in the loop on twitter for the latest teardown shenanigans.
In case you missed it, last week we celebrated a major milestone. In addition to enabling Apple repair, we now have parts and repair manuals for most game consoles! We decided to celebrate by taking a trip through time and ripping apart five retro consoles.
Shameless plug: We fund teardowns like this by selling iPod Touch Parts! We've also got free open-source repair manuals for every iPod Touch but this one, and we're working on that.

iPod Touch 4th Generation Teardown
¶
We've got the new iPod Touch in hand!
The feature set of the new Touch is suspiciously similar to the iPhone 4:
640 x 960 pixel resolution retina display
Rear-facing camera with 720p video recording
Front-facing camera with VGA video recording
802.11b/g/n Wi-Fi
FaceTime video chat
Three-axis gyro

Step 2
¶
The new Touch has a visible speaker grill on the bottom (to the left of the dock connector). On previous iPod Touches, the external audio simply came out the dock connector. Apple likely beefed up the speakerphone to enable FaceTime on the Touch.
The new Touch has once again been slimmed-down. Similar to the iPhone 4, the back of the Touch is now flat. Unlike the iPhone 4, the iPod Touch still features the same shiny aluminum back that has graced every iPod Touch.
We paid $229 for our 8 GB Touch, which seems like a pretty good deal. A 32 GB Touch will set you back $299, and a 64 GB can be had for $399.
Bogus math: In dollars per gigabyte, the 8 GB Touch is a terrible deal: $28.63/GB. With the 64 GB Touch a gigabyte will only cost you $6.23.
Want bogus logic to go with our bogus math? BusinessWeek has a fallacious column up on how the iPod Touch costs $29 more than the iPhone 4.

Step 3
¶
The new Touch (right) with its retina display doesn't look exceptionally remarkable in this shot.
The retina display features a resolution of 640x960. Compared to the previous Touch (320x480), that's twice pixels in each direction, or four times the total pixels.
The retina display is almost completely black when turned off. That's noticeably different from the display of the earlier iPod Touch (left), which is dark gray when turned off.

Cameras!
That's right folks, at long last the iPod Touch has not one, but two cameras.
The front-facing camera is just like that of the iPhone 4, with support for VGA quality photos and video.
Unfortunately, the rear-facing camera is only 960x720 resolution. That's only about .7 megapixels, compared to 5 megapixels on the iPhone 4. It's likely that Apple had to sacrifice still photo resolution in order to squeeze the camera into the Touch's slim package.
There's a microphone hole next to the rear camera. Apple's updated the audio input and output prowess of the new Touch to enable it to play nice with FaceTime.

Step 5
¶
Enough of the exterior, let's get inside...
There are no visible screws. We'll have to figure out what combination of glue, tabs, and magic Apple used to hold the Touch together.
We first used a heat gun to soften the adhesive holding the display assembly in place.
Next, we ran a iPod Touch opening tool around the edge to separate the adhesive.

Edit
Step 6
¶
That was the easiest iPod Touch we've ever cracked open. Hopefully the insides will continue to be repair-friendly.
Dear iFixit: this is Future iFixit and we can confirm that the insides are not repair-friendly.
The display assembly is still attached to the iPod, and disconnecting it doesn't look like it's going to be easy.

Edit
Step 7
¶
Like the iPhone 4, it appears that the front glass and LCD panel are permanently fused together. The good news is that this will prevent dust from getting beneath the glass, but unfortunately it will make repair more expensive.
There are two cables securing the display assembly to the logic board. One is easy to disconnect, but the other is more challenging. The thin black cable connects beneath the logic board. That means that replacing the display assembly will definitely not be trivial.
If you have a 1st, 2nd, or 3rd generation Touch, it is possible to replace just the front glass without replacing the LCD.

Edit
Step 8
¶
There's an EMI shield between us and the iPod. Fortunately, it's just held in place with a few Phillips #00 screws.
The EMI shield is surprisingly heavy, weighing in at 11 grams. The entire iPod Touch is only 101 grams, meaning Apple has devoted more than 10% of the iPod's weight to this metal EMI shield.
