港版iPhone 6网络支持实测：不支持电信CDMA
　　苹果iPhone 6与iPhone 6 Plus面世，发布会上官方宣称其网络能力得到提高，基本满足了全球范围内的LTE
4G国际漫游，做到真正的全网通手机，意味着只要你拿着无锁的iPhone
6/6P，在国家之间漫游穿梭，均能够无缝接入当地的高速网络。虽然暂时国内iPhone
6行货的开售日期尚未确定，但是从运营商透露出的信息来看，iPhone 6与iPhone 6 Plus不锁网的几率很大。
　　在行货开售前，我们拿到了港版的iPhone 6(型号A1586)，官网资料显示港版iPhone 6公开销售的无锁版能够支持联通、移动和电信的2G/3G/4G网络，也就是我们俗称的全网通，那么事实是否真的如此？一起来实测。
　　iPhone 6网络版本解析
　　其实早在发布会后，iPhone 6能够实现全网通的消息已经在苹果官网得到证实，公开无锁版本型号为A1586的iPhone
6和A1524的iPhone 6 Plus，这两款型号能够支持GSM/EDGE/TD-SCDMA/WCDMA/CDMA
EV-DO/FDD-LTE/TD-LTE网络，也就是支持国内三大运营商的2G/3G/4G网络。
　　只要是公开无锁的裸机版本，包括日本、香港、美国等地销售的版本都能够实现全网通，因此理想状态下只要使用无锁版本，那么便能够支持国内或者国际任何一 家运营商的网络。当然这只是在理想状态下，苹果会因应当地的政策在软件系统方面对全网通的iPhone
6进行屏蔽，硬件基础是支持的，只是进行系统方面的软屏蔽。
香港公开无锁版本为A1586和A1524
　　港版裸 机无锁公开版，型号为iPhone 6(A1586)，iPhone 6 Plus
(A1524)，硬件支持全网通，CDMA网络硬件基础支持，但是因为香港并没有CDMA运营商，默认应该会软屏蔽，需要添加运营商配置文件等方式才可以 完美支持。在国内直营店可享受完美的联保换机政策。这也是国内用户最喜欢的版本。
　　三大运营商实测
　　iPhone 6(A1586)硬件上是能够支持全网通的，那么直接放三大运营商的4G卡看看能够支持。
　　中国移动
　　其实自从iPhone 5s/5c港版能够支持移动4G后，iPhone 6港版必然也会默认开放TD-LTE 4G网络，不出意外，iPhone 6港版能够完美使用中国移动2G/3G/4G网络，并不需要任何破解，原生支持。
移动4G可以轻松上
　　测速显示中国移动4G网络已经渐趋成熟，下行和上行速度稳定，商用已经接近1年的时间，下行基本稳定在30Mbps左右。
　　中国联通
　　联通拥有最成熟和最国际的WCDMA 3G网络，而在4G采用TD/FDD的混合组网，现在实行试点的城市当中大部分已经开放了FDD的网络授权。iPhone 6港版能够支持联通2G/3G/4G网络，不需要破解，插卡即用。
　　广州已经是联通4G混合组网试点城市，从网络信息可以看到其连接得3频段，属于FDD频段。测速成绩比较优秀，但现阶段联通基本只在广域进行了覆盖，重点区域等地依然靠3G网络承担。
　　中国电信
　　中国电信3G网络模式为CDMA，而4G同样为TD/FDD混合组网。iPhone 6港版虽然网络硬件基础上能够支持CDMA、TD-LTE和FDD-LTE，但是因为香港并没有CDMA运营商，默认情况下是不能使用电信网络。
激活或插卡后会短暂搜到电信信号
　　不过笔者发现，插入电信4G卡进行iPhone 6港版激活时可行的，同时也会短暂出现网络标识和信号，而4G标识也会出现，但是当激活完毕后便回到无服务的状态。
关于本机里面电信网络显示
信号不能固定
　　打开关于本机页面，运营商会显示中国电信，但是搜索不了信号，仍然处在无服务状态。因此港版iPhone
6实际硬件是能够支持，但是因为政策等一些原因，CDMA电信网络是软屏蔽的。此外中国电信网络暂时并未部署SRLTE和SVLTE，因此即使 iPhone 6能搜索到4G信号，也不能回落到CDMA电路域进行通话。因此电信用户要想使用4G，时间还早着。
　　虽然港版iPhone
6并没能成为传闻中的全网通神机，不过能够原生通吃移动和联通的2G/3G/4G网络，已经能解决大部人的需求。电信用户继续杯具，iPhone
6港版并不能系统原生支持CDMA，但是如同iPhone 5港版当初的情景一般，国内高手可能很快能通过技术手段令港版iPhone
6用上电信网络，拭目以待。

The iPhone 3G is a
that was designed and marketed by
generation of , successor to the , and was introduced on June 9, 2008, at the
The iPhone 3G is internally similar to its predecessor, but included several new hardware features, such as ,
/. The device was originally loaded with the concurrently launched . In addition to other features (including
and ), this new operating system introduced the —Apple's new distribution platform for third-party applications.
On July 11, 2008, Apple released the iPhone 3G across twenty-two countries in two storage options, 8GB and 16GB. The 16GB model was produced in either black or white.
Following the release of the successor
model one year later, the iPhone 3G remained on sale but became Apple's budget phone offer, with its price cut in half. This $99 iPhone 3G required a two-year contract and was available only in black and with 8 GB of storage, but came bundled with the then-new iPhone OS 3.0 firmware. On June 7, 2010, the iPhone 3G was finally discontinued, and replaced as Apple's budget phone by an 8GB iPhone 3GS selling for the same price of $99 with a 2-year contract.
The iPhone 3G came preloaded with the latest version of iPhone OS, and continued to receive updates to its software for over two years, with major iterations released on an annual basis. However, the phone had access to a decreasing proportion of new features with each update as its hardware became superseded by later models.
When it was launched, the iPhone 3G came preloaded with . This introduced the App Store, Microsoft Exchange ActiveSync support, Apple’s MobileMe service, and push email support, along with other new features and bug fixes.
In June 2009, iPhone 3G users received the
software update, which introduced the long-awaited
feature, copy and paste, landscape support for more applications,
stereo support, and other improvements.
In June 2010, Apple released the
software update. Unlike its successor models, the iPhone 3G does not support important features of iOS 4.0 such as multitasking, the ability to set a home screen wallpaper, or Bluetooth keyboard support. However, it does provide access to a unified mailbox feature, homescreen folders to better organize apps, playlist creation, and other enhancements. This update was widely criticized for slow performance on iPhone 3G, though September 2010's iOS 4.1 release resolved this problem. However, unlike more modern iOS devices, this update again does not provide iPhone 3G owners with access to important features, in this case the Game Center application.
On November 22, 2010, the iPhone 3G received the iOS 4.2 software update (as iOS 4.2.1), which introduced features such as YouTube voting, and security fixes. However, the iPhone 3G is unable to use many features included in this update, such as AirPlay and Safari Text Search. This is the last iOS release to support this iP iOS 4.3 and later are not compatible with this iPhone model due to hardware limitations and performance issues.
A rear view of the
(left) made of aluminum and plastic, and the iPhone 3G, made entirely from a hard plastic material.
The iPhone 3G's back featured a redesigned
plastic housing, replacing the aluminum back of the first generation. Buttons were changed from plastic to metal, and the edges of the phone were tapered, providing a better grip. The iPhone 3G introduced the first official color options for the outer casing, with the 16GB version available in black and white.
The dimensions of the iPhone 3G were marginally larger than those of the original iPhone. It was 116 millimetres (4.6 in) high, 62 millimetres (2.4 in) wide, and 12 millimetres (0.47 in) deep, compared to its predecessor, which was 110 millimetres (4.3 in) high, 61 millimetres (2.4 in) wide, and 12 millimetres (0.47 in) deep.
The iPhone 3G sported a 3.5 in (89 mm) capacitive touchscreen with a 480×320 () resolution at 163 . The scratch-resistant glass sits on top of the display. Just like the original iPhone, the touchscreen was designed for a bare finger, or multiple fingers for multi-touch sensing. The device featured the same sensors as its predecessor. The proximity sensor (which deactivates the display during calls when the face is near) was repositioned to save battery power and to prevent inadvertent inputs from the user’s face and ears. An ambient light sensor was included to adjust the display brightness for different lighting conditions, which helps save battery power. A 3-axis
was included to sense the orientation of the phone and change the screen accordingly, allowing the user to easily switch between portrait and landscape mode.
Most of the iPhone 3G's internal hardware is based on the original . It still includes a
620 MHz processor (underclocked to 412 MHz), a
MBX Lite 3D , and 128 MB of
On the rear of the device, the iPhone 3G features the same fixed-focus 2.0
camera of its predecessor. This camera does not have optical zoom, flash, autofocus, or native video recording, although various applications became available to allow video recording on the device. The iPhone 3G's operating system supports the
of photographs.
In addition to EDGE, the iPhone 3G supports ,
/. These enhancements allow faster data downloads and
with maps compared to previous devices.
Like its predecessor, the iPhone 3G features a proprietary 30-pin dock connector for charging the device. It can also be used to synchronize the device with a computer and to connect various accessories.
The iPhone 3G features a flush-mounted 3.5 mm headphone jack instead of the recessed headphone jack that was included on the original iP it could therefore be used with headphones other than those provided by Apple.
The iPhone 3G features an internal rechargeable battery rated at 1150 mAh, which, like its predecessor, is not user-replaceable. Apple stated that the iPhone 3G’s battery is capable of providing up to six hours of web browsing via Wi-Fi, or five hours via 3G, or 25 hours of audio playback. Alternatively, it is said to provide 300 hours of standby time.
This section needs expansion with: actual reviews. You can help by . (October 2014)
described the device as "a more capable version of an already excellent device." However, he said that it had "hidden costs."
4, which was still compatible with the iPhone 3G, was released on June 21, 2010. An article in the Wall Street Journal's Digits column on July 28, 2010 reported that iPhone 3G phones updating to iOS 4 responded slowly, had diminished battery life, and became excessively hot.
