  1. 新的iPod touch 3代来啦! 它有三种配置可选,其中32GB和64GB的型号有着更快的处理器而且支持OpenGL ES 2.0。
    • 新的iPod touch 3代来啦!

    • 它有三种配置可选,其中32GB和64GB的型号有着更快的处理器而且支持OpenGL ES 2.0。

    • 我们认为8GB的型号没有任何改变。唯一确知的是它的价格改为了$199。

    • 菲利普·席勒说:“$199是个iPod中屡试不爽的价格。”不过,似乎人们并不介意多付些钱。苹果已经卖出了两千万部iPod touch,价格都在$199之上。

  2. 我们有一部32GB的touch。它的外观看上去完全没变,但是刻着新的型号标识“A1318”,而 第二代touch是A1288。(其实标注容量的小框也变小了——译者注)

    • iPod touch不像它的小弟弟——新款nano——一样受宠。仍然没有摄像头。

    • 总而言之,如果你又想要触摸屏又想要摄像头,那就只能选iPhone了。

  3. 我们还在进行拆卸。现在先看看一些有趣的数据吧。
    • 我们还在进行拆卸。现在先看看一些有趣的数据吧。

    • 在美国64GB touch的定价是$399,折合下来你要为每GB容量付出$6.23。这可比不上160GB iPod classic每GB $1.56的价格。

    • 回溯四年看,初代的nano每GB合$62.23,而iPod Video这款硬盘机每GB合$6.65。

    • 有意思的是,可以看出今天单位闪存的价格大概持平四年前单位硬盘的价格。2005年你可以花$399买60GB的iPod Video,而现在你可以在同样的价钱买到64GB的iPod touch。

    • 不用把这些数字看得太重,iPod上除了存储介质意外,还有部件成本和其他附加成本。

    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.

  4. 据苹果说,新款的touch可快多达50%。拿它的性能PK iPhone 3GS想来亦可赛艇。 拆开这部iPod不容易。没错,我们最近一直这么评价iPod……不幸的是,现在卖的iPod没有一款是好拆的。
    • 据苹果说,新款的touch可快多达50%。拿它的性能PK iPhone 3GS想来亦可赛艇。

    • 拆开这部iPod不容易。没错,我们最近一直这么评价iPod……不幸的是,现在卖的iPod没有一款是好拆的。

    • 前玻璃面板兼触摸屏总成与前作不一样。该部件在我们这里最受欢迎。我们已经有一代二代的了,很快也会把这一代的补上。

    Probably for the mic I wish they remembered to install

    Gun - 回复

    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!

    • 飞利浦00号螺丝刀很快就卸下了将LCD固定在touch的螺丝。

    • 这块LCD与第二代touch的很像但是不尽然一样。显示屏的连接器宽一点点。

    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.

    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.

  8. 电池2.92瓦时或789毫安时。
    • 电池2.92瓦时或789毫安时。

    • 多亏苹果把瓦时数打印在电池上,免了我们很多麻烦。

    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

  9. 剥去扬声器就是touch的内脏。
    • 剥去扬声器就是touch的内脏。

    • 在这里,三星恐成最大赢家!

    • ARM处理器标着:

    • 339S0075 ARM

    • K4X2G303PE-SGC8

    • YNE069AC 0928

    • APL2298

    • 这是个新的、更快的处理器吧?前一代iPod touch(第二代)上的处理器标着339S0048ARM,而iPhone 3GS的处理器标着339S0073ARM。

  10. 三星的NAND闪存。
    • 三星的NAND闪存。

    • 有两块128Gb装的芯片,加起来是256Gb。把数字除以8就得到这MLC NAND闪存容量32GB。

    • 我们移走扬声器时芯片就是这样,不是我们造成了损伤。我们不清楚那只是粘合剂,还是芯片真的有点化掉了。

    "We're not sure if that's just adhesive, or if the packages were actually slightly melted"

    it looks like super glue!

    • 8GB第二代touch主板(左)与我们新的32GB第三代touch主板。

    • 两部机型基本设计一样。但是,第三代上,NAND闪存分为了两块芯片,在板子上留不下什么空隙了。(但第二代大容量的型号难道不也是这样吗?——译者注)

  13. 高通BCM4329FKUBG无线芯片。 根据高通的资料,BCM4329是支持802.11n的!
    • 高通BCM4329FKUBG无线芯片。

    • 根据高通的资料,BCM4329是支持802.11n的!

    • 这可不得了了,因为就算iPhone 3GS也不支持802.11n。iPhone 3GS使用BCM4325无线芯片,那只支持802.11 a/b/g。尚不知道802.11n会在软件中得到支持,不过硬件是有了。

    • 芯片还集成有蓝牙2.1 + EDR及FM的收发器。如果装有天线,而且苹果在软件里增加了支持,理论上你可以在车上播放音乐流而无须再加配件。不过这很大程度上是假想。

    I want an FM transmitter in my iPhone 3GS! That would rock...and roll?

    Brady Cabe - 回复

    来自 brady 的话:

    I want an FM transmitter in my iPhone 3GS! That would rock...and roll?

    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.

    rrrob - 回复

    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)?

    fernandokreutz - 回复

    So, how do I get one of those 802.11n chips into my 3Gs?

    geneh56 - 回复

    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.

    Francy - 回复

    Does the 8 GB touch include the 802.11n chip, or just the 32 and 64 GB models?

    Phishy - 回复

    来自 Francy 的话:

    If they have the 4329 in them then why don't the devices support the 5GHz radio band?

    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.

  14. 看上去苹果在设备顶部为摄像头预留了空间。高通芯片和无线天线之间有块6毫米×6毫米×3毫米的空间。这对于iPhone那样的自动对焦照相镜头来说不够深,但装iPod nano第五代里的摄像头刚好。 看上去苹果在设备顶部为摄像头预留了空间。高通芯片和无线天线之间有块6毫米×6毫米×3毫米的空间。这对于iPhone那样的自动对焦照相镜头来说不够深,但装iPod nano第五代里的摄像头刚好。 看上去苹果在设备顶部为摄像头预留了空间。高通芯片和无线天线之间有块6毫米×6毫米×3毫米的空间。这对于iPhone那样的自动对焦照相镜头来说不够深,但装iPod nano第五代里的摄像头刚好。

    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.

    1comment - 回复

    I think it should be mentioned that, based on position and the "cutout" on the underside of the front bezel, this space looks like it was meant for a forward facing camera; which, as 1comment pointed out, would make it tough to sell the nano or iPhone on the basis of their cameras.

    That area could expand enough for a camera... apple will probably give it to samsung to do, just like every one else it seems.

    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.

Can u put it back together and still have a ipod that works?

Annie - 回复

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.
