这台机子没有sim卡插槽，根据苹果的说法，在GSM版iPhone4中，sim卡和卡托是唯一可供用户维修的部件，苹果现在说“iPhone不包含任何用户可维修的部件。”我们相信你有权维修自己的硬件，我们会马上提供维修指南。
-
我们认为手机右侧天线的额外隔断是从GSM切换到CDMA的结果，天线的工作频率直接取决于它的尺寸和几何结构，因此这种改变需要对天线进行大量修改。
-
GSM版iPhone有三个不同形状的天线，使手机能够在UMTS/HSDPA/HSUPA（850、900、1900、2100 MHz）和GSM/EDGE（850、900、1800、1900 MHz）上进行通信。
-
CDMA版iPhone有四段天线（顶部和底端是两个U型条，边缘是两个直条）CDMA只需要在800MHz和1900MHz频率下运行
-
这两款手机的蓝牙使用2400 MHz频率，WiFi使用2.4 GHz，A-GPS使用1.575 GHz频率。
-
只有时间能证明这种新的天线设计是否有助于解决据报道困扰AT＆T的GSM iPhone 4的接收问题。但是，没有理由指望它，因为据报道，在全球其他GSM网络上的GSM iPhone不会出现此问题。
AFAIK the 802.11n radio on the iPhone 4 doesn't supports the 5Ghz frequency band
So how can one find the SIM card # on the A1349 model?

背部盖板非常相似，但不通用，只是看起来像而已
-
我很好奇在你史诗般的环游世界的旅途中你应该带上什么机
-
维基百科只列出了大约40个国家的58家CDMA运营商，以及近300家GSM/UTMS运营商
-
如果你只能带一部手机，请坚持使用GSM版本。但是，如果你迫切希望在美国获得更可靠的覆盖范围，Verizon将为您提供一款免费的“国家兼容”手机，为期三周。

Clearly a new A4 version from Apple:
- different Apple PoP part number 339S0123 (original iPhone 4: 339S0108)
- different Samsung DRAM incorporated K4265J1PB-50-F (original iPhone 4: K4X4G643GB)
- same processor SoC die marked as APL0398
Guys...I think you miss the BCM4329 on one of the module as the WIFI chip bigtime...... the readers are not well inform.

I have solder an A4 CPU from iPhone 4 CDMA to iPhone 4 GSM after restore it works as it should.

高通MDM6600支持高达14.4Mbps的HSPA+数据速率和CDMA2000® 1xEV-DO Rev. A/Rev. B
-
这个芯片和全球手机Droid Pro一样，那台手机GSM和CDMA都支持-意味着苹果肯定支持GSM，但是刻意把它砍掉了
-
为何苹果砍了GSM呢？可能是因为设计只支持CDMA的天线更容易--这个机子只支持两个蜂窝频段，而GSM版支持5个
-
当然，没有sim卡槽的手机怎么可能成为真正的“全球手机”呢？
-

-
乍一看这个屏幕总成和GSM版本没啥变化

我们很快就会有替换用的零件和详细的维修指南
This right here is the $100,000 question. Stick one of your existing AT&T iPhone 4 front assemblies on this bad boy and see if it fires up!
You guys (rab777hp and jonathan) are joking, right? There is no way that can be done in the current config. h/w and s/w wise. The VZW iPhone doesn't have the front end parts for UMTS at all and you can't just connect some ATT iPhone front end to it cuz the interfaces and architecture used by the 2 phones aren't compatible. Besides, the s/w (protocol stack & firmware) for UMTS are not resident in the VZW iPhone version. Once again, you can't just borrow firmware from the ATT iPhone and try to shove it into the VZW version. They are simply not compatible between the 2 phones. The most one can say from the choice of this chip is that Apple is positioning itself to use this chip as a reconfigurable modem (at the time of manuf.) to support CDMA and UMTS when the iPhone5 comes out.

My names Kyle, I have managed to remove the vibrator from the bottom and cut out the mounting tabs for the logic board that kept it from seating. Once I set the board in I did a little bit of ribbon folding to put them on the gsm board attached the wifi antenna from the gsm and put the battery in it and it fired right up. Now the only downside at all is that you have to put the SIM card in when you're putting the board in unless you want to cut a slot in the side and due to water and everything I decided against it. Just modify the tray and slide the sun card in the slot and put the phone together and you're good. Oh yeah, and you have to cut a tab off of the back glass if you want to use your att one.

"On the back, Apple's removed the visual warning to not throw your iPhone 4 in the trash."
This is the <a href="http://en.wikipedia.org/wiki/Waste_Elect...>WEEE</a> directive logo which applies to electronics sold in (most) of the EU. The Verizon iPhone is only sold in the USA at present so the directive doesn't/can't apply.
Hey guys this is a question! I need help! I have (two) IPhones. I need to swap the logic boards. Will it still work without a SIM card since the model:A1332 has one and the logic board I'm installing has no SIM card?
Thank you When I try to repair my iphone I found a very little part, now I know the part name "Wi fi ground finger". At first I never knowing where come from. thanks to this diagrams I fix it. Thank you so much
