The iPod Touch is a portable media player and Wi-Fi mobile platform designed and marketed by Apple Inc. The product was launched on September 5, 2007 through an event called The Beat Goes On.1 The iPod Touch adds the multi-touch graphical user interface to the iPod line and is available with 8, 16, or 32 GB of flash memory. It includes Apple's Safari web browser and is the first iPod with wireless access to the iTunes Store. With a software update, which is sold by Apple, it also has access to Apple's App Store.2 The second generation iPod Touch, featuring external volume controls, a built-in speaker, a contoured back and built-in Nike+ support, was unveiled on September 9, 2008 at the Let's Rock keynote presentation.

The iPod touch has the iPhone's multi-touch interface, with a physical home button off the touch screen. The home screen has a list of buttons for the available applications. All iPod touch models have included the applications Music, Videos, and Photos (collectively duplicating the standard functions of the iPod Classic), iTunes (providing access to the Wi-Fi Music Store), Safari, YouTube, Calendar, Contacts, Clock, Calculator, and Settings. Later models added Mail (accessing POP/IMAP/SMTP e-mail), Maps, Stocks, Notes, and Weather,3 which could also be added to the earlier models with the purchase of a $20 software upgrade. Direct links to web sites can be added to the home screen by the user (called "Web Clips").
On July 11, 2008 the iPhone 2.0 software was released for the iPod Touch for $9.95. The update allowed 1st generation iPod touches to access the App Store, download third party applications, in addition to a host of minor "fixes".
As supplied new, the iPod Touch needs a connection to a computer for initial configuration.4 Officially, Apple requires iTunes to be installed on either a Mac OS X or Windows operating system based computer for configuring the iPod Touch. On either operating system, the iPod Touch must be connected through a USB port.5 The first time the iPod Touch is turned on, a "connect cable to iTunes" graphic will be displayed continuously until the iPod Touch is connected to a computer running iTunes. 6
To use the iPod Touch for buying products at the iTunes Wi-Fi Music Store via Wi-Fi, an iTunes Store account must be created in iTunes and the account details then entered into the iPod.7
Apple states that the following is required for the iPod Touch:5

The iPod touch is equipped with Wi-Fi 802.11b/g, and, like the iPhone, includes the Safari browser and a viewing client for YouTube. The device's Wi-Fi capabilities can also be used to buy music from the iTunes Wi-Fi Music Store. The iPod touch 2.0 Software Update supports WPA2 Enterprise with 802.1X authentication.10
Shortly after the iPod Touch was released (firmware release 1.1.1), hackers were able to "jailbreak" the device through a TIFF exploit. The resulting application, "Installer.app", enabled the user to download a selection of unofficial third-party programs. Some of these give the user more control over the iPod Touch than is officially available, and also makes it work on Linux operating systems. Firmware versions 1.1.2, 1.1.3, 1.1.4, 1.1.5, 2.0, 2.0.1, 2.0.2, 2.1, and 2.211 can also be jailbroken. Only first generation iPods could be jailbroken, since the newest generation has a different processor. Servicing an iPod Touch after jailbreaking or other modifications made by unofficial means is not covered by Apple's warranty.
A software development kit (SDK) was officially announced on March 6, 2008, at an Apple Town Hall meeting.12 The iPhone SDK allows developers to make applications for the iPhone and iPod Touch after paying a fee to join the development team. The developer can then set the price for the applications they develop and will receive 70% of the sale price after each one is sold in the exclusive App Store. The developer can also opt to release the application for free and will not pay any additional costs. Apple released the 2.0 firmware upgrade on July 11, 2008, which includes the App Store.
Thomas Fessler, the CEO of Handheld Games Corp, a developer of third-party games for the iPod Touch and iPhone, reported that the performance of its 3D game TouchSports Tennis varied across different models, with the 2nd-generation iPod Touch delivering significant performances increases over its predecesor and both iPhone models.13 This is attributed to the increased processor speeds in the 2nd-generation iPod Touch, though Fessler speculates that other factors may have contributed to it.
The iPod Touch is slimmer and lighter than the iPhone. It lacks some of the iPhone's features: access to a phone network, a built-in microphone, a camera, Bluetooth capability, and GPS receiver. Steve Jobs has referred to the iPod Touch as "training wheels for the iPhone."14
The second generation has an added volume rocker and a built-in speaker, which were previously iPhone-only features. The second generation also comes with the chrome frame seen on the iPhone 3G, making the two almost identical when viewed from the front, with the only differences being no speaker above the screen, no silent/ringer switch and the sleep/wake button on the other side. The second generation also supports audio input when a headphone or earphone with microphone capabilities is plugged into the audio output jack. Although unannounced and unsupported by Apple, the iPod Touch has Bluetooth capability, as the included WiFi chip (Broadcom BCM4325) has Bluetooth and FM Radio support, as well as the advertised Wi-Fi capability.15 It is believed that this Bluetooth capability is being used for Nike+iPod support, as Apple has said that the Nike+iPod kit works on an unspecified 2.4 GHz radio frequency.

2nd Generation iPod Touches have a yellower cast to the display, although it is unclear whether this will affect video playback drastically. Users have reported a reduction in display quality with this tint.16
| “ | When you compare the second-generation iPod touch to the original iPod touch or an iPhone, you’ll find its screen “warmer” (read: yellower) in cast. With the iPhone 3G, Apple moved to this warmer display tone because it felt it provided the best look for all the content the device was capable of playing—meaning photos and video. The latest iPod touch’s screen is even more yellow than the iPhone 3G’s. Apple claims this was a deliberate choice rather than some kind of power-saving measure or a result of the native characteristic of the display components.
When viewed side by side with an older iPod touch or an iPhone — particularly when looking at a settings screen that has a lot of white on it — the 2G iPod touch’s display looks dingy in comparison. But put those other devices aside, use the iPod touch as it was intended, and you’ll forget all about its warmer cast.17 |

The first generation iPod Touch works with all Made for iPod peripherals, but Apple made changes to the iPod Touch 2G that prevent many existing peripherals from recharging the updated player.18 The iPod Touch 2G, along with the iPhone 3G, no longer supports charging through FireWire connections for peripherals, and causes them to function improperly. These peripherals include some speaker systems like the Bose Sounddock.citation needed
