Mengintip Jeroan IPOD

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

Spoiler for Opening the Ipod: 

That was the easiest iPod Touch we've ever kracked 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.


Like the iPhone 4, it appears that the front glass and LCD panel are permanently fused together

There are two cables securing the display assembly to the logic board. One is easy to disconnect, but the other is more challenging.

NOTE:If you have a 1st, 2nd, or 3rd generation Touch, it is possible to replace just the front glass without replacing the LCD.

Spoiler for Bongkar isi Ipod: 

Unlike the iPhone 4, the fourth generation Touch's rear-facing camera does not support autofocus and is a much lower resolution.
For those of you who are wondering, there's no way the iPhone 4's rear camera can be installed in the Touch without some extreme hackery.
This camera is 6.5 mm square by 3.3 mm tall. That is dramatically smaller than the iPhone 4's rear camera.
Just above the rear camera, the cylindrical silver object is the microphone, a new feature for the iPod Touch line.

Spoiler for IPOD Camera: 

The front-facing camera is readily accessible and can be disconnected from the logic board at this point.
We're not surprised: they have the same resolution.
This camera is 4.9 mm square and 2.5 mm thick, slightly (0.3 mm) thinner than the iPhone 4's front facing camera.

Spoiler for Ipod Wifi: 

As you can see this antenna is presumably used for Wi-Fi reception and is situated near the front glass panel when the Touch is completely assembled. Its new location eliminates the need for the plastic "window" found on the 3rd generation Touch.'

Finally! We found some serious chips.
(Red Frame)The key marking of interest on the A4 processor package is K4X2G643GE. This is identical to the marking found on the iPad processor, but different from the iPhone 4 processor. The iPad has 256 MB RAM, while the iPhone 4 features 512 MB. Unfortunately, this means that like the iPad, the new iPod Touch includes only 256 MB of RAM.
(Blue Frame) The NAND flash memory is now provided by Toshiba, not Samsung like that of the iPad.
(Orange Frame)Probably the WiFi and Bluetooth-Chip.
And no, there's no RAM upgrade slot.

Spoiler for IPOD Logic Board: 

There are a few more chips at the other end of the logic board.
(Red Frame) On the far left is a 338S0859 chip. It's similar to the Cirrus Logic audio codec of the iPhone 4 (338S0589).
(Yellow Frame) The new AGD8 2032 gyroscope is very similar to that one of the iPhone 4.
(Orange Frame) The 2032 33DH chip is found next to the gyroscope. It seems this chip was packaged in the same die with the gyroscope in the iPhone 4.
You can clearly see the 30 pins of the dock connector, located just below the row of chips.



The iPod Touch now has a legitimate speaker, although we doubt it'll satisfy many audiophiles.
Apple appears to be routing the audio out not only the newly-added speaker grill (large hole), but also out of the dock connector (small hole).

Spoiler for IPOD 4G: 

What's this? Empty space?
We don't know what this white plastic piece does other than take up space. Perhaps it's a weight-saving device.


--------------------------------------------------------------------------

iPod Touch 4th Generation Repairability: 4 out of 10 (10 is easiest to repair)
Good: Opening the device is pretty straightforward, as long as you have a heat gun and some iPod Touch opening tools handy.
Good: The headphone jack is not soldered to the logic board, a first for the iPod Touch line.
Bad: The front glass and LCD are permanently fused together, increasing the cost of repairing broken front glass.
Bad: Removing the display completely requires removing the logic board
Bad: Apple soldered the volume button and sleep button cable to the logic board. The previous Touch had a ZIF connector. This makes removing logic board very difficult.
Bad: The battery is still soldered to the logic board, just like previous models.
