iPhone 3GS adalah layar sentuh ponsel pintar, dirancang dan dipasarkan oleh Apple Inc.. Ini adalah ketiga generasi iPhone, penerus iPhone 3G. Itu diperkenalkan pada tanggal 8 Juni 2009, di WWDC 2009 yang berlangsung di Moscone Center, San Francisco. Peningkatan termasuk kinerja, kamera dengan resolusi dan kemampuan video yang lebih tinggi, kontrol suara, and support for 7.2 Mbit/s HSDPA downloading (but remains limited to 384 kbps uploading as Apple had not implemented the HSUPA protocol). It was released in the U.S., Canada and six European countries on June 19, 2009, di Australia dan Jepang pada tanggal 26 Juni, dan secara internasional pada bulan Juli dan Agustus 2009. IPhone 3GS menjalankan sistem operasi iOS Apple, seperti yang digunakan pada iPad dan iPod touch. Sebagian besar dikendalikan oleh ujung jari pengguna pada layar multi-sentuh. Itu berhasil sebagai smartphone andalan Apple pada tahun 2010 oleh iPhone 4, namun 3GS terus diproduksi hingga September 2012 ketika iPhone 5 diumumkan.

Sejarah

IPhone 3GS tersedia untuk pre-order pada 8 Juni 2009 dan dirilis pada 19 Juni di Kanada, Amerika Serikat, dan 7 negara Eropa, dan pada 26 Juni di Australia dan Inggris. Dalam minggu pertama peluncurannya, lebih dari satu juta iPhone 3GS terjual, dan Agustus 2010 dirilis iPhone 3G[S] secara internasional.

Fitur

Fitur-fitur baru dari iPhone 3G[S] utamanya adalah perubahan internal terkait kecepatan, yang merupakan singkatan dari "S" dalam "iPhone 3GS". Meskipun selain peningkatan terutama mengenai kinerja, berbagai fitur perangkat lunak juga diperkenalkan secara eksklusif untuk iPhone 3GS. Semua fitur eksklusif dimasukkan ke dalam iPhone 4.

Menampilkan

Tampilan LCD pada perangkat dirancang oleh Apple dan dibuat oleh LG. Ini menampilkan layar sentuh kapasitif dengan kerapatan piksel 163 piksel per inci (ppi) pada layar 35 in (89 cm) 480-kali-320. Perbaikan pada layar pendahulunya termasuk emulasi warna 24-bit (tampilan warna 18-bit plus dithering)

Kamera

IPhone 3GS memiliki fitur kamera 3,2 megapiksel yang ditingkatkan yang diproduksi oleh OmniVision. Selain jumlah megapiksel yang lebih tinggi, ia juga memiliki fitur fokus otomatis, keseimbangan putih otomatis, dan makro otomatis, serta mampu merekam video VGA. Aplikasi Kamera iPhone 3GS memiliki fitur slider yang memungkinkan pengguna untuk beralih antara mengambil foto dan merekam video, fitur tap-to-focus yang memungkinkan pengguna untuk mengetuk area gambar kamera untuk fokus otomatis, 5x digital zoom (iOS 4 dan 5), fokus otomatis dan kunci eksposur otomatis saat menahan area (hanya iOS 5), dan garis kisi untuk komposisi (hanya iOS 5).

Prosesor dan memori

IPhone 3GS ditenagai oleh chip Samsung APL0298C05, yang dirancang dan diproduksi oleh Samsung. System-on-a-chip ini terdiri dari inti CPU ARM Cortex-A8 yang di-underclock hingga 600 MHz (dari 833 MHz), terintegrasi dengan PowerVR SGX 535 GPU. Ini memiliki 256 MB eDRAM, dua kali lipat dari 3G, memungkinkan peningkatan kinerja dan multi-tugas. Apple mengklaim iPhone 3GS 2x lebih cepat dari pendahulunya, menunjukkan demonstrasi berbagai aplikasi yang dimuat dalam waktu setengah dari pendahulunya.

Penyimpanan

Seperti pada model sebelumnya, semua data disimpan di memori flash dan bukan di SIM dan tidak menawarkan opsi apa pun untuk memperluas penyimpanan. Awalnya hanya tersedia dalam 16 dan 32 GB meskipun model 8 GB kemudian dirilis, dengan Apple menghentikan model 16 dan 32 GB, memaksa mereka yang membutuhkan penyimpanan lebih untuk memilih iPhone 4, atau membeli model lama 3GS.yar sentuh kapasitif]] dirancang untuk jari telanjang, atau beberapa jari untuk penginderaan multi-sentuh.

Power and battery

The iPhone 3GS is powered by an internal 3.7 V 1219 mAh rechargeable lithium-ion polymer battery and is designed to retain up to 80% of its original capacity after 400 full charge and discharge cycles. A battery life indicator in percentage was also exclusive to the iPhone 3GS.

Apple claims that the 3GS can last for up to ten hours of video, nine hours of web browsing on Wi-Fi, twelve hours of 2G talk time, or five on 3G, 30 hours of music, or 300 hours of standby.

Magnetometer

A magnetometer is also built-in the iPhone 3GS, which is used to measure the strength and/or direction of the magnetic field in the vicinity of the device. Sometimes certain devices or radio signals can interfere with the magnetometer requiring users to either move away from the interference or re-calibrate by moving the device in a figure 8 motion. The iPhone 3GS also features a Compass app which was unique at time of release, showing a compass that points in the direction of the magnetic field.

Connectivity

In addition to the iPhone 3G's Tri-band UMTS/HSDPA radio and quad-band GSM/GPRS/EDGE radio, the 3GS also adds support for 7.2 Mbit/s HSDPA allowing faster downlink speeds though upload speeds remain the same as Apple had not implemented the HSUPA protocol. Other updates include the addition of a built-in Nike+iPod sensor which eliminates the need for an external sensor and allows native Nike+iPod support. The Bluetooth server on the iPhone 3GS has also been slightly improved adding support for Bluetooth 2.1 specifications.

Voice control

Voice Control was introduced as an exclusive feature of the iPhone 3GS and allows for the controlling of the phone and music features of the phone by voice. There are two ways to activate Voice Control: hold the Home button while in the home screen for a few seconds; or, change the effect of what double-clicking the home button does so it will activate Voice Control (only before iOS 4, where double clicking the Home button opens the multitasking bar).

Accessibility features

VoiceOver, Color Inversion, and Text Zoom were introduced as exclusive features to the iPhone 3GS. VoiceOver is a feature that dictates music details, system menus, text, and other things which was first introduced on the third generation iPod shuffle. Color inversion reverses the color scheme from black on white to white on black, while Text Zoom allows users to zoom into a text on the screen .

Design

The reverse of the iPhone 3G (left) is almost identical to that of the 3GS, except for the latter's reflective silver text which now matches the silver Apple logo, replacing the 3G's grey text.

The iPhone 3GS retains the design of the 3G, with a glossy plastic back with tapered edges and metal buttons. The 3GS has reflective silver text on the reverse side which matches the silver Apple logo, replacing the 3G's grey text. Unlike its predecessor, the iPhone 3GS was available in white and black for (16 GB and 32 GB), although the 8 GB model is only available in black.

Critical reception

Reviews of the iPhone 3GS have been generally mixed to favorable. Walter Mossberg of The Wall Street Journal described the device packed with "new features that makes a great product even better, but for many users, the software may be enough of a boost to keep them from buying the new model." Engadget also said that "the additions of video recording, a compass, and a speed bump just don't seem that compelling to us".

The device managed to receive numerous favorable reviews. CNET gave the iPhone 3GS 4 out of 5 stars, citing battery life improvements and speed bump. Engadget praised the performance improvements.

The 8 GB version received more favorable reviews mainly because it comes pre-installed with iOS 4. Jason Snell of Macworld praised the iPhone 3GS, saying that "the device's internal changes shines in the iOS 4 update, making the iPhone 3GS a worthwhile upgrade compared to its predecessor although a little too late compared to the iPhone 4". TIPB stated that "aside from hardware specific features like FaceTime, Retina Display, and gyroscope support, the bottom line is iPhone 3GS users are getting the same software that makes the iPhone 4 great".

Issues

Overheating

Shortly after the release of the iPhone 3GS, some users reported overheating of the device while in heavy use, and others reported discoloration of the device due to heat (particularly on the white models). The discoloration issues were largely discounted as being as a result of iPhone covers rubbing against the back of the iPhone.

Apple responded to the heat issue reports by warning users against leaving their iPhones in a car on a hot day, leaving it in direct sunlight for extended periods of time, and refraining from heavy usage while in a hot/sunny environment. It is also worth pointing out the temperature specifications in which the iPhone should be operated, which follows safety standards in the countries the 3GS was released.

Continued support

iOS 5

After the release of the iPhone 4S, the 3GS was still offered for free until November 2011, when AT&T raised the price to 99 cents with no explanation as to why. The 99c price is only available with a two-year contract on AT&T in the United States and a three-year contract on Telus, Rogers, Bell and Fido Solutions in Canada. This is a departure from Apple's previous trends, in which only two phones were sold.

New Bootrom and 2011 Baseband Update

On September 9, 2009, Apple launched an updated model of the iPhone 3GS that patched a segment overflow in the SecureROM of the Device that had allowed loading an unsigned LLB.

After the release of the iPhone 4S, Apple killed the unlock for the new iPhone 3GS devices that were produced after week 36th of 2011 by updating its baseband hardware from an Infineon Baseband chip to a Toshiba Baseband chip. Although the new chip uses the same modem firmware as the Infineon chip, it cannot be updated to iPad baseband 06.15.00 that is still vulnerable to the AT+XAPP exploit.

iOS 6

The iPhone 3GS has become the only iPhone to support 4 generations of the iOS software. People were unsure as to why Apple made the decision to support the 3GS, but not the first generation iPad and earlier models of the iPod touch which share the same specifications. Although the 3GS is still supported, some major features of iOS 6 aren't supported. This however holds true for the iPhone 4 as well. Features such as Flyover and 3D Maps aren't featured on either phone. The 3GS seems to be well supported by Apple in regard to the iPhone 4. Whereas the 3GS got nearly all the features from 3 major OS releases (3, 4, 5), the iPhone 4 only got full features from 2 major OS releases (4, 5), and got only partial support on iOS 6. This can be attributed to the relatively larger performance improvement of the 3GS in relation to other iPhone generations. On September 12, 2012, Apple announced that they will no longer sell the iPhone 3GS at their stores or on Apple.com.

The decision to support the 3GS instead of the iPad (which has a faster processor) has been open to wide debate. General consensus has been that the iPad is no longer sold, whereas the 3GS still is. However many people, especially developers, have stated that although the iPad has superior hardware, its hardware is still proportionally weaker than the 3GS. The iPad has more than quadruple the pixels to power than the 3GS, yet still uses the same graphics processor. The iPad also has the same amount of RAM, 256 MB, which in proportion to its screen resolution, is hardly enough. The only hardware advantage the iPad has is a faster processor. However, the processor is not enough to make up for the lack of RAM and graphics power. As a result, there have been numerous complaints on the performance of iOS 5 on the iPad. The 3GS, on the other hand, had generally positive reviews of smooth performance on iOS 5 (some even claim better performance), making it still a good candidate for iOS 6. On September 12, 2012, Apple announced that they will no longer be selling and supporting the iPhone 3GS, therefore meaning iOS 6 will be the final iOS to support the 3GS. The iPhone 3GS currently supports iOS 6.0.1, Apple's latest iOS.
