The iPod Touch (trademarked iPod touch) also known as the iTouch 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. 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.
Description
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 iTunes 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, which could also be added to the earlier models with the purchase of a software upgrade. Direct links to web sites can be added to the home screen by the user.
New applications including a VPN client, scientific calculator and access to third party applications were released for a small upgrade fee on July 11 2008. For more details on this topic, see iPhone OS version history.
Requirements
As supplied new, the iPod Touch needs a connection to a computer for initial configuration. 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. The first time the iPod Touch is turned on, a "cable to iTunes" graphic will be displayed continuously until the iPod Touch is connected to a computer running iTunes.
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.
Apple states that the following is required for the iPod Touch:
- A computer running either:
- iTunes 7.7 (with the 2.0 iPhone OS update) or 7.6 for iPhone OS 1.1.4 or earlier
- Available USB 2.0 port

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.
Third-party applications
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, and 2.0 can also be jailbroken. Servicing an iPod Touch after jailbreaking or other modifications made by unofficial means is not covered by Apple's warranty.
A software development kit was officially announced on March 6, 2008, at an Apple Town Hall meeting. 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.
Comparisons to the iPhone
The iPod Touch is slimmer and lighter than the iPhone. It lacks some of the iPhone's features: access to any phone network, an internal speaker, a microphone, a camera, physical buttons for volume control, Bluetooth capability and Assisted GPS. The iPod Touch uses software-based volume controls which require users to double-tap the home button, bringing up an on-screen slider.
Early screen problems
A number of early adopters complained that the screen could not properly display shades of black. The problem has been attributed to poor quality control and the misapplication of the reflective coating on the LCD. The defect caused the screen to have a very narrow optimal viewing angle and also resulted in "shimmering" blacks. This screen problem was later addressed with the firmware update 1.1.1, with mixed results. Apple has replaced iPod Touch models with persistently defective screens. This problem was seen in the iPod Touch models that were distributed in November 2007 to late January 2008.
