在我的相册

里面有最新的图片。

看了国内外的报道，所谓的拆解（当然我相册里面的那些水印也就不可信啦。。。）其实根源都来自iFixit

大家如果看iFixit的英文有困难，可以直接看engadget上翻译的文章，比较原汁原味。

当然，也不是说除了iFixit就乏善可陈——

msn的tw版本的3C频道报道：iPhone 4 拆解：電池大了 19%

Gizmodo貼出iPhone 4照片最引人詬病之處是沒有貼出內裝的照片，僅有這張，但這張也只是要證明這是蘋果OEM硬體而已。

大家最想知道的CPU、Wi-Fi硬體，甚至micro SIM 都沒看到圖片。有些照片，比如下面這張，雖然有貼出邏輯板，但卻都被遮蔽住了，作者Jason chen擔心打開有可能會搞壞機器。拿來跟先前iFixit貼出的iPhone 3GS內裝照作比較：差很大吧。

iFixit的Kyle Weins向外界表示，這支 iPhone 4 DVT 版本（Design Verification Testing）已經相當接近生產階段。Weins擔心這支外流的DVT版 iPhone 硬體有可能讓外界的期待過高，畢竟有時在生產前最後一刻還是會移除某些功能。以下是Gizmodo貼的零件大合照：Giz的結論是，蘋果有縮小零件，好讓機器更輕薄，大約比3GS少了3公克，不過電池有大了約19%，其他則都縮小了。

大概就是這樣了，Giz拆了iPhone 4，但又擔心搞壞機子，所以沒有回答到大家最想知道的部分：蘋果是否有把iPad那顆A4晶片拿來用在新版iPhone 4硬體上？我猜應該有。

EDN美国编辑Brian的报道：A Two-Day Early Score: iFixit Tears Down The Apple iPhone 4

墨说：其实这篇文章分析得最为透彻了。包括了不少工程师关心的设计问题，我稍后贴在最后，英文的就是了，有兴趣的筒子们，可以尝试翻译。

Briand Dipert原文：

Head here for the play-by-play dissection. Some highlights, at least as I see ‘em:

• As previously rumored, the iPhone 4 contains 512 MBytes of system DRAM. This compares with 256 MBytes on the iPhone 3GS and first-generation iPad, and 128 MBytes on prior-generation iPhones and iPod touches. Limited system memory is fundamentally what precludes multitasking on iOS v4 with 128 MByte-inclusive gear. I suspect that its also behind the fact that iMovie for iOS v4 is only supported on the iPhone 4. And web surfing may be an added motivation for more RAM. Others’ reviews (I haven’t personally noticed this) suggests that browsing is on average slower with the iPad than with the iPad 3GS; even though both units contain identical RAM allocations, the iPad’s screen resolution is substantially larger. The iPhone 4G is in a similar pixel-count situation, and the 2x multiplier may be intended to provided more cache memory for Mobile Safari.
• Like the Google Nexus One, the iPhone 4 contains dual microphones (one each at the top and bottom of the handset) for dynamic ambient noise reduction purposes. And as previously mentioned by yours truly, it offers a tandem of cameras; a rear-facing 5 Mpixel one that also delivers 720p video capture (and with a notable resolution up-tick versus the 2 Mpixel iPhone 3G and 3 Mpixel iPhone 3GS, which respectively do CIF and VGA video capture, the former only when jailbroken) and a front-facing VGA one for FaceTime and other videoconferencing, etc. apps.
• The Broadcom BCM4329 802.11n/Bluetooth 2.1+EDR/FM and BCM4750I A-GPS ICs are (not surprisingly) re-used from the iPad 3G design, along with the Cirrus Logic 338S0589 audio codec.
• Once again, STMicroelectronics supplied the 3-axis accelerometer. And in a first-time entrant to the Apple product portfolio, the iPhone 4G also contains a silicon MEMS gyroscope. EDN published a contributed article from Analog Devices on the topic in mid-May, but iFixit believes that this particular IC is also sourced from STMicro. For existing designs that might want to emulate the gyro function via a software upgrade using an available accelerometer, GPS receiver and silicon compass, check out this recent writeup. I also spoke at length on the emulation topic yesterday with Freescale, who doesn’t yet have a gyro in its product portfolio.
• I’ll just quote this one directly from the email iFixit sent me: “In what can only be described as a work of genius, Apple has integrated the UMTS, GSM, GPS, Wi-Fi, and Bluetooth antennas into the stainless steel inner frame.” Pretty slick (see photo below)…
• And speaking of reuse (and again not surprising), Apple has expanded the usage footprint of the A4 ARM-based microprocessor beyond the iPad to the iPhone 4. In my comments the other day, I didn’t mention (in the interest of space) how impressed I was with the notably enhanced speediness of the iPad versus my iPhone 3G, in spite of the tablet’s ~4x-multiplied display resolution. Granted, the CPU in the iPhone 3G is two generations old; I’ll shortly be rectifying that discrepancy to a degree. Still, I’m quite impressed with the system boot-up, application start-up and other performance metrics that the iPad exhibits. A recent deep-dive analysis contradicts earlier reports that the A4 CPU is identical to the S5PC10 in recent Samsung mobile electronics devices, although it points out that the two processors are very similar. For more on A4 performance, check out the on-iPad benchmark studies conducted by AnandTech, Twitterific developer Craig Hockenberry and Gizmodo.
