iPhone 3G

the iPhone 3G is a smartphone designed and marketed by Apple Inc. This is the second generation of the iPhone, the successor to the original model, unveiled on June 9, 2008 at WWDC 2008, held at the Moscone Center in San Francisco.

This device, although internally similar to its predecessor, has several significant hardware improvements. Among them were a GPS module, 3G data support and tri-band UMTS/HSDPA. the iPhone 3G was equipped with the latest version of the operating system, then known as iPhone OS 2. This software brought with it a number of new features, such as push mail support and turn-by-turn navigation. However, the most groundbreaking innovation was the introduction of the App Store, a new distribution platform for third-party applications created by Apple.

Premiere and availability

The official launch of the iPhone 3G took place on July 11, 2008, when the device was launched in twenty-two countries simultaneously. Consumers could choose between two capacity versions: 8 GB and 16 GB. The 16 GB model was available in two color options: black and white. In the U.S. market, the iPhone 3G was offered only with AT&T's two-year carrier plan. The starting price was $199 for the 8 GB model and $299 for the 16 GB version.

Evolution of the offer

A year later, after the release of its successor, the iPhone 3GS, the 3G model remained in Apple's portfolio as a budget option, offered at a discounted price. This version of the iPhone 3G, available for $99, required a two-year contract and was only available in black with 8 GB of memory. In addition, the device came with the new iPhone OS 3.0 operating system. For customers preferring a no-obligation purchase, AT&T offered the iPhone 3G for $499 (8 GB) or $549 (16 GB) in 2009.

on June 7, 2010, Apple officially ended production of the iPhone 3G. Its place in the budget range has been taken by the 8 GB iPhone 3GS, selling for $99 with a two-year contract.

Curiosity

It is interesting to note that in 2008, Import Genius, a company that provides business information for the import-export industry, used electronic customs clearance data published by U.S. Customs and Border Protection under the Freedom of Information Act to detect the arrival of the iPhone 3G even before Apple's official announcement. This shows how much interest and anticipation accompanied the launch of this device.

Software

The evolution of the operating system

the iPhone 3G was equipped with an advanced operating system that evolved over the life of the device. At launch, the smartphone shipped with iPhone OS 2 preinstalled, the latest version of the software at the time. For more than two years, users received updates to the system, with major iterations released annually. It is worth noting, however, that as time went on and newer iPhone models appeared, access to new features in updates for the iPhone 3G was gradually limited due to hardware limitations.

iPhone OS 2

the iPhone OS 2, pre-installed on the iPhone 3G, introduced several groundbreaking features. The most important of these was the App Store, a distribution platform for third-party applications. In addition, the system offered support for Microsoft Exchange ActiveSync, Apple's MobileMe service, and push mail support. The update also brought a number of other improvements and bug fixes.

iPhone OS 3

In June 2009, iPhone 3G users received an upgrade to iPhone OS 3. This version of the system introduced the long-awaited MMS feature, copy and paste capability, expanded support for landscape mode in more applications, Bluetooth stereo support, and many other improvements.

iOS 4.0 and later

The next major update, iOS 4.0, was released in June 2010. However, unlike newer models, the iPhone 3G did not support some of the key features of iOS 4.0, such as multitasking, the ability to set a wallpaper on the home screen, or support for the Bluetooth keyboard. The update, however, introduced a unified inbox feature, folders on the home screen for better organization of applications, creation of playlists and other improvements. It is worth noting that the update has received criticism due to its slow performance on the iPhone 3G. However, this problem was resolved in September's iOS 4.1 update. Nevertheless, as with newer iOS devices, this update did not give iPhone 3G owners access to important features, in this case the Game Center app.

on November 22, 2010, the iPhone 3G received an update to iOS 4.2 (version 4.2.1). This version of the system introduced features such as YouTube voting and security fixes. However, the iPhone 3G was unable to use many of the features included in this update, such as AirPlay and text search in Safari. Significantly, this was the last version of iOS to support this iPhone model. iOS 4.3 and later versions are not compatible with iPhone 3G due to hardware limitations and performance issues.

Compatibility with applications

It is also worth mentioning that virtually all apps released after the release of iOS 6 in late September 2012 do not work on the iPhone 3G. This is because the software development kit (SDK) has been changed so that it no longer allows "targeting" (minimum requirements) of iOS versions older than 4.3 (including 3.x and up to 4.2.1) or devices with ARMv6 processor (first two generations).

In summary, the history of the iPhone 3G software shows how Apple has tried to keep older hardware up to date while introducing new features. However, hardware limitations eventually led to the end of support for this model, which is typical in the rapidly evolving world of mobile technology.

Hardware specifications

Construction and design

the iPhone 3G introduced significant changes in design and hardware specifications compared to its predecessor. The most noticeable change was the polycarbonate housing, which replaced the first generation's aluminum design. The back of the device has been redesigned, and the buttons have been changed from plastic to metal. The edges of the phone have been rounded for a better grip. the iPhone 3G was the first model to offer official case color variants - the 16 GB version was available in both black and white.

Dimensions

The dimensions of the iPhone 3G differed slightly from the original. The device was 116 mm high, 62 mm wide and 12 mm thick, a slight increase over its predecessor (110 mm x 61 mm x 12 mm).

Display

The iPhone 3G screen remained unchanged from its predecessor. It was a 3.5-inch (89 mm) capacitive touchscreen with a resolution of 480x320 pixels (HVGA), which translated to a density of 163 pixels per inch. The display was protected by scratch-resistant glass. Like the original iPhone, the touchscreen was designed to be operated with a bare finger or several fingers for multi-touch gestures.

Sensors

the iPhone 3G retained most of the sensors familiar from its predecessor, but made some improvements. The proximity sensor, which turns off the display during phone calls, has been repositioned to save power and prevent accidental touches to the screen by the user's face or ear. The device also included an ambient light sensor that automatically adjusted the brightness of the display according to lighting conditions, helping to save battery life. In addition, the iPhone 3G was equipped with a three-axis accelerometer that detected the phone's orientation and rearranged the screen accordingly, allowing the user to easily switch between portrait and landscape mode.

Processor and memory

In terms of performance, most of the internal hardware components of the iPhone 3G were based on the original iPhone. The device features a Samsung 32-bit ARM11 RISC processor clocked at 620 MHz (overclocked to 412 MHz), PowerVR MBX Lite 3D GPU, and 128 MB of DRAM with package on package (PoP) technology.

Camera

The iPhone 3G's camera remained unchanged from its predecessor. On the back of the device was the same camera with a fixed focal length and 2 megapixel resolution. It had no optical zoom, flash, autofocus or native video recording capability, although various apps allowed video recording on the device. IPhone 3G operating system introduced support for geotagging photos.

Connectivity

In terms of connectivity, the iPhone 3G has made some significant improvements. In addition to EDGE, the device now supported Assisted GPS, 3G data and tri-band UMTS/HSDPA. These improvements have enabled faster data download and turn-by-turn navigation with maps compared to previous devices.

Connectors

Like its predecessor, the iPhone 3G had a proprietary 30-pin dock connector for charging the device. It could also be used to synchronize the device with a computer and connect various accessories. Unlike the original iPhone, which had a recessed headphone jack, the iPhone 3G was equipped with a standard 3.5mm headphone jack, making it possible to use any headphones, not just those supplied by Apple.

Battery

The iPhone 3G battery, like its predecessor, was not user-replaceable. The internal 1150 mAh battery, according to Apple's statement, provided up to six hours of Internet browsing via Wi-Fi or five hours via 3G, or 25 hours of audio playback. Alternatively, the device could remain in standby mode for 300 hours.

In summary, the iPhone 3G introduced a number of hardware improvements, while retaining many features of its predecessor. Design changes, the introduction of GPS and 3G, as well as minor improvements in the areas of sensors and connectivity, have made it a significant step forward in the evolution of the iPhone lineup.

Acceptance and technical problems

General perception

the iPhone 3G, despite being a significant step forward in Apple's smartphone lineup, was met with a mixed reception and encountered some technical problems after its release. Reactions to the device have been mixed, with users reporting various difficulties with its operation.

Walt Mossberg, an acclaimed technology reviewer for The Wall Street Journal, described the iPhone 3G as "a more advanced version of an already excellent device." However, he also pointed out the "hidden costs" associated with its use. This opinion reflected the general mood around the device - enthusiasm about the new features, but also caution about potential additional expenses.

Connectivity problems

Shortly after its release, the iPhone 3G began to suffer from several significant technical problems. Users reported frequent interruption of phone calls and slow internet connections. These connectivity problems have become the subject of extensive analysis and discussion.

Analysis by various sources pointed to a particular chip inside the phone as the main culprit for connectivity problems. Apple, instead of carrying out a costly and complicated replacement of the devices, decided to solve these problems through a software update. The update likely modified the operation of the problematic chip, resulting in improved call quality and Internet connection speeds for iPhone 3G users.

It is interesting to note that despite numerous user reports of connectivity problems, AT&T - the main iPhone 3G carrier in the United States at the time - presented a different position. In an official statement, the company said: "Overall, the new iPhone works great on our 3G network." This discrepancy between user experience and the operator's position has sparked additional controversy and discussion in the technology media.

Battery and performance issues

Another serious problem that affected the iPhone 3G was excessive battery consumption after upgrading to iOS 4. IOS 4, which was still compatible with the iPhone 3G, was released on June 21, 2010. An article published in the Wall Street Journal's "Digits" column on July 28, 2010 reported that 3G iPhones after upgrading to iOS 4 ran slowly, had significantly reduced battery life, and got excessively hot.

Battery problems were particularly frustrating for users because they significantly affected daily use of the device. Many users reported that their phones were discharging much faster than before the update, in some cases rendering the device virtually useless without frequent charging.

Excessive heat was not only inconvenient for users, but also raised concerns about the safety and durability of the equipment. In extreme cases, users reported that their 3G iPhones became so hot that it was difficult to hold them in the hand.

Applications

These problems showed that although the iPhone 3G was still compatible with newer versions of the operating system, as an aging piece of hardware it had difficulty supporting increasingly demanding software. This has highlighted the challenges smartphone manufacturers face as they try to balance support for older devices with the introduction of new features and enhancements.

In summary, the iPhone 3G, although a significant step forward in the evolution of the iPhone, encountered a number of challenges after its release. Connectivity, performance and battery life issues after system updates have highlighted the complexity of developing and maintaining advanced mobile devices. Despite these difficulties, the iPhone 3G remained an important part of Apple's smartphone history, paving the way for future innovations and improvements in subsequent models.
