The iPhone 3G is the second smartphone in the iPhone range of Apple. It was introduced on June 9, 2008 at the WWDC 2008 at the Moscone Center in San Francisco.
On the iPhone 3G Apple's iOS is used. With the introduction of version 2.0 has been supplied, the highest supported by Apple version is 4.2.1. This was published on 22 November 2010. Subsequent iOS versions are no longer supported by the iPhone 3G. Mainly the device is operated by finger contacts on the multi -touch screen.

Predecessor is the original iPhone; Successor to the iPhone 3GS.
Since June 7, 2010, a few weeks before the release of the iPhone 4, the official sale is complete set.
Design
Compared to the previous model, the corners of the unit were rounded and thinner. The aluminum housing has been replaced by a back made of black plastic. The reason for better reception performance was given at lower power. The 16- gigabyte model was also available in white.
Specifications
Main processor
The iPhone 3G uses a manufactured by Samsung ARM11 processor which is clocked at 412 MHz. The name of the processor is S5L8900, it is the same processor as the first iPhone and the iPod touch first generation. The processor supports ARMv6, a 32- bit architecture.
Mobile and Networking
As announced by the Chief Executive Officer Steve Jobs already in September 2007, the communication capabilities of the iPhone have been extended. The most significant innovation was the support of UMTS mobile phone. Furthermore, the use of HSDPA, an improvement of UMTS, possible, where is the network side supports.
Digital camera and memory
The built-in 2 - megapixel camera corresponds to the camera from the first generation. However, video programs now were available, their use, however, is much to the detriment of the battery. The quality of the recorded video should be easily improved in the successor model.
The iPhone 3G features (depending on model) for an 8 or 16 GB of NAND flash memory for data and a RAM of 128 MB. After the introduction of the iPhone 3GS, the iPhone 3G was made only in the 8- GB version.
Location
With the built-in GPS module, it is possible to determine the exact position and display it in Google Maps; assumes an active Internet connection to retrieve the card material. Third parties such as Navigon and TomTom have developed iPhone versions of their navigation software and published in the App Store. Some critics complained that the GPS antenna is too small for accurate location - however many tests reported accurate location. In addition to the GPS position data and A - GPS information of mobile phone masts and Wi-Fi access points are used to enable the localization without GPS ( eg in buildings ), and generally to improve the accuracy.
Many programs available to use the GPS module, for example, a spilled way to understand or to determine the speed.
Prices
The prices at two -year contract binding were decreased compared to the previous model; in the U.S., the iPhone 3G, for example, for $ 199 (8GB ) or $ 299 (16 GB) has been available in Germany subsidized by T -Mobile price was depending on the tariff binding for the 8 GB version between a euro and 169.95 EUR, or between 19.95 euros and 249.95 euros for the 16 GB version.
Criticism
After the software update to version iOS 4 in June 2010, partly massive performance problems were encountered while iPhone 3G. It took twice the time to respond to inputs compared with the previous software iPhoneOS 3.1.3. This problem is due to the extensions of the functionality in iOS 4. Although Apple had a lot of functions are not enabled on the iPhone 3G was the main processor is still not strong enough, and the memory was 116 MB dimensioned too small to provide an attractive usability of iOS 4. The resulting also from this problem the user store for the iPhone 3G is in iOS 4 only 84 MB; for the SpringBoard and additionally running application programs is not sufficient. Apple has tried to improve the performance with updates, improvements, however, were moderate, so that Apple was sued for lies and deceptions regarding the performance of the iPhone 3G. The iPod touch 2nd generation, which is the iPod touch counterpart to the iPhone 3G was not as severely affected by this problem, since it is the opposite SoC ( S5L8720 ) is used, which has a more powerful architecture as the S5L8900 the iPhone 3G and is also operated at a higher clock frequency, resulting in a better performance.
A larger number of users complained about poor reception and connectivity issues with the iPhone 3G. A statement by Apple, there are not on this issue. In August 2008 it was reported by conjecture, according to which the problems could have been caused by supplied by Infineon, immature UMTS chipsets.
