iPhone 3G

The iPhone 3G is the second generation of iPhone. It was the successor to the original iPhone, and is succeeded by the iPhone 3GS. Introduced on June 9, 2008 at the WWDC 2008 at the Moscone Center, San Francisco. The 3G was very similar to its predecessor, containing the same 2 MP camera and no support for video recording, and its performance was limited by the same 128 MB eDRAM memory unit.^[12] Nevertheless, the 3G featured several improvements over the original. It supported Assisted GPS, 3G data and Tri-band UMTS/HSDPA.

The iPhone 3G runs Apple’s iOS operating system, the same operating system used on previous iPhones, the iPad, the Apple TV, and the iPod Touch. It is primarily controlled by a user’s fingertips on the multi-touch display, which is sensitive to fingertip contact.

The iPhone 3G no longer receives software updates from Apple. The last release of iOS to support the 3G was 4.2.1, which was released on November 22, 2010. iOS 4.3, released on March 11, 2011, did not support the iPhone 3G

History

On July 11, 2008, Apple released the iPhone 3G in twenty-two countries, including the original six; in 8GB and 16GB models, with the larger capacity version having the option of being in black or white.

When the iPhone 3GS was released one year later, the iPhone 3G's price was cut in half, and was made the budget model of iPhone. The $99 iPhone 3G was in black only and came with 8GB of storage. Included with this revision is iPhone OS 3.0 On June 7, 2010, the iPhone 3G was discontinued, and replace with an 8 GB iPhone 3GS selling for the same price of $99.

Software

The iPhone 3G came preloaded with the latest version of iPhone OS both to offer the newest improvements to the software and to combat efforts of jailbreaking. Over the years, the iPhone 3G has been supported by Apple with software updates. Major iterations of the software usually released yearly.

At launch, in July 2008, the iPhone 3G came preloaded with iPhone OS 2.0 which introduced the App Store, Microsoft Exchange ActiveSync support, Apple’s MobileMe service, and push email support, along with other new features and bug fixes as well.

On June 2009, the iPhone 3G received the iPhone OS 3.0 software update which introduced the long-awaited MMS feature, copy and paste, landscape support for more applications, Bluetooth stereo support, and other improvements as well.

On June 2010, the iPhone 3G owners were issued the iOS 4.0 software update. Unlike its successor, the iPhone 3GS, it did not receive multitasking, home screen wallpaper, or Bluetooth keyboard support. However, it still got the unified mailbox feature, folders, playlist creation, among other enhancements in iOS 4. Still despite the number of new features the update introduced, it was widely criticized for its slow performance on the device.

However an update to iOS 4.1 was unveiled and released on September 2010 which improved the device’s performance under iOS 4. Unlike other iOS devices though, it did not receive the Game Center application.

On November 22, 2010, the iPhone 3G received the iOS 4.2 software update, which included new features such as YouTube voting, and security fixes. The iPhone 3G however did not receive many features including AirPlay, more options in the multitasking tray, and Safari Text Search.

On January 12, 2011, the iOS 4.3 software update beta 1 was issued to developers. However, there are no iPhone 3G download links. The iPhone 3G is no longer supported by Apple in software updates.

On March 9, 2011, the iOS 4.3 software update officially announced, which was the first iOS software update leaving out the support of iPhone 3G.

iPhone

The iPhone (pronounced /ˈaɪfoʊn/ eye-fohn) is a line of Internet and multimedia-enabled smartphones marketed by Apple Inc.. The first iPhone was unveiled by Apple's then-CEO Steve Jobs on January 9, 2007, and released on June 29, 2007. The 5th generation iPhone, the iPhone 4S, was announced on October 4, 2011, and released on October 14, 2011, two days after the release of iOS 5.0, the Apple operating system for handheld devices.

An iPhone can function as a video camera (video recording was not a standard feature until the iPhone 3GS was released), a camera phone, a portable media player, and an Internet client with email and web browsing capabilities, can send texts and receive visual voicemail, and has both Wi-Fi and 3G connectivity. The user interface is built around the device's multi-touch screen, including a virtual keyboard rather than a physical one. Third-party as well as Apple application software is available from the App Store, which launched in mid-2008 and now has over 500,000 "apps" approved by Apple. These apps have diverse functions, including games, reference, GPS navigation, social networking, security and advertising for television shows, films, and celebrities.

There are five generations of iPhone models, each accompanied by one of the five major releases of iOS (formerly iPhone OS). The original iPhone was a GSM phone that established design precedents like screen size and button placement that have persisted through all models. The iPhone 3G added 3G cellular network capabilities and A-GPS location. The iPhone 3GS added a compass, faster processor, and higher resolution camera, including video recording at 480p. The iPhone 4 has a rear facing camera (720p video) and a front facing camera (at a lower resolution) for FaceTime video calling and for use in other apps like Skype. The iPhone 4 featured a higher-resolution 960x640 display; it was released on June 24, 2010. In the U.S., AT&T was the only authorized carrier until February 10, 2011, when a CDMA version of the iPhone 4 launched for Verizon. On October 4, 2011, Apple announced the iPhone 4S.The iPhone 4S added a higher resolution camera (8 megapixel) with 1080p video recording, face detection, and video stabilization, a faster, dual core processor, world phone capability (allowing a single handset to operate on networks based on both GSM/UMTS and CDMA technologies), GLONASS support and a natural language voice control system called Siri. It will be available in 16 GB and 32 GB as well as a new 64 GB capacity. It was also announced that in the U.S. Sprint would begin carrying the iPhone 4 and iPhone 4S and C Spire Wireless announced that it would be carrying the iPhone 4S as well.

Yahoo ! Messeger

Yahoo! Messenger (sometimes abbreviated YIM) is an advertisement-supported instant messaging client and associated protocol provided by Yahoo!. Yahoo! Messenger is provided free of charge and can be downloaded and used with a generic "Yahoo! ID" which also allows access to other Yahoo! services, such as Yahoo! Mail, where users can be automatically notified when they receive new email. Yahoo! also offers PC-PC, PC-Phone and Phone-to-PC service, file transfers, webcam hosting, text messaging service, and chat rooms in various categories.

Yahoo! Messenger was originally launched under the name Yahoo! Pager on March 9, 1998.

In addition to instant messaging features similar to those offered by ICQ, it also offers (on Microsoft Windows) features such as: IMVironments (customizing the look of Instant Message windows, some of which include authorized themes of famous cartoons such asGarfield or Dilbert), address-book integration and Custom Status Messages.It was also the first major IM client to feature BUZZing and music-status. Another recently added feature is customized avatars. Yahoo Messenger also allows users to access Yahoo Chat Rooms.

Ipod

iPod is a line of portable media players created and marketed by Apple Inc. The product line-up currently consists of the hard drive-based iPod Classic, the touchscreen iPod Touch, the compact iPod Nano, and the ultra-compact iPod Shuffle. iPod Classic models store media on an internal hard drive, while all other models use flash memory to enable their smaller size (the discontinued Mini used a Microdrive miniature hard drive). As with many other digital music players, iPods can also serve as external data storage devices. Storage capacity varies by model, ranging from 2 GB for the iPod Shuffle to 160 GB for the iPod Classic. The iPod line was announced by Apple on October 23, 2001, and released on November 10, 2001. All of the models have been redesigned multiple times since their introduction. The most recent iPod redesigns were introduced on September 1, 2010.

Apple's iTunes software can be used to transfer music to the devices from computers using certain versions of Apple Macintosh and Microsoft Windows operating systems.^[2] For users who choose not to use iTunes or whose computers cannot run iTunes, several open source alternatives are available for the iPod.^[3] iTunes and its alternatives may also transfer photos, videos, games, contact information, e-mail settings, Web bookmarks, and calendars to iPod models supporting those features.

For iOS versions prior to iOS 5, the iPod branding is also used for the media player applications included with the iPhone and iPad; the iPhone version is essentially a combination of the Music and Videos apps on the iPod Touch. (As of iOS 5, separate apps named 'Music' and 'Video' are to be standardized across all iOS-powered products.^[4]) In either event, the iPhone and iPad have essentially the same media-player capabilities as the iPod line, but they are generally treated as separate products.

Discontinued models of the line include the iPod Mini and the iPod Photo, the former being replaced by the iPod Nano, and the latter reintegrated into the main iPod line (now the iPod Classic).

Macintosh

The Macintosh (pronounced / mak-in-tosh), or Mac, is a series of several lines of personal computers designed, developed, and marketed by Apple Inc. The first Macintosh was introduced by Apple's then-Chairman Steve Jobs on January 24, 1984; it was the first commercially successful personal computer to feature a mouse and a graphical user interface rather than a command-line interface.The company continued to have success through the second half of the 1980s, only to see it dissipate in the 1990s as the personal computer market shifted toward the "Wintel" platform: IBM PC compatible machines running MS-DOS and Microsoft Windows.

Years later, Apple consolidated its multiple consumer-level desktop models into the 1998 iMac all-in-one. This proved to be a sales success and saw the Macintosh brand revitalized, albeit not to the market share level it once had. Current Mac systems are mainly targeted at the home, education, and creative professional markets. These include the descendants of the original iMac and the entry-level Mac mini desktop models, the Mac Pro tower graphics workstation, the MacBook, MacBook Air and MacBook Pro laptops. The Xserve server was discontinued January 31, 2011.

Production of the Mac is based on a vertical integration model in that Apple facilitates all aspects of its hardware and creates its own operating system that is pre-installed on all Mac computers. This is in contrast to most IBM PC compatibles, where multiple sellers create and integrate hardware intended to run another company's operating software. Apple exclusively produces Mac hardware, choosing internal systems, designs, and prices. Apple does use third party components, however, such as graphics subsystems from nVidia and ATi. Current Mac CPUs use Intel's X86-64 architecture; the earliest models (1984–1994) used Motorola's 68k and models from 1994–2006 used the AIM alliance's PowerPC. Apple also develops the operating system for the Mac, currently Mac OS X version 10,7 "Lion". The modern Mac, like other personal computers, is capable of running alternative operating systems such as Linux , FreeBSD and, in the case of Intel-based Macs,Microsoft Windows, However, Apple does not License Mac OS X for use on non-Apple computers.
