The iPod Touch (colloquially iTouch,) is a portable media player, personal digital assistant, handheld game console, and email-capable Wi-Fi mobile device designed and marketed by Apple Inc. It is not a smartphone.

The iPod Touch adds the multi-touch graphical user interface to the iPod line. It is the first iPod with wireless access to the iTunes Store, and also has access to Apple's App Store, enabling content to be purchased and downloaded directly on the device. As of July 2012, Apple has sold 82 million iPod Touch units.

Software

The iPod Touch runs iOS. The first major update after the initial release was iPhone OS 2.0. This update introduced the App Store, which allowed third-party applications for the first time. iPhone OS 2.0 debuted July 11, 2008. iPhone users received the update for free, iPod Touch users were charged. The second major update to the operating system, iPhone OS 3.0, was released June 17, 2009. iPhone OS 3.0 added features such as cut, copy, and paste, data tethering and push notification support. As with the prior major release, iPhone users received the update for free, iPod Touch users again were charged. iOS 4.0 was made available to the public on June 21, 2010. It was the first major iOS release to drop support for some devices; the first generation iPod Touch and original iPhone are not supported in iOS 4.0. The iPhone 3G and second generation iPod Touch had limited functionality under iOS 4.0, while the iPhone 4, iPhone 3GS, third generation iPod Touch, and fourth generation iPod Touch had full functionality under iOS 4.0. The major features introduced in iOS 4.0 included iBooks, FaceTime, and multitasking. iOS 5.0 was previewed to the public on June 6, 2011, and was released on October 12, 2011.

Apple has received criticism for charging iPod Touch owners for major iOS updates that iPhone owners receive for free, as well as excluding certain features from the iPod Touch software that are included in the iPhone. Apple has said that they can add features for free to the iPhone because the revenue from it is accounted for on a subscription basis under accounting rules, rather than as a one time payment. At WWDC in June 2010, Steve Jobs announced that Apple had "found a way" to make subsequent OS upgrades available free to iPod Touch owners. However, iOS 4.0 and onwards isn't available for the first generation iPod Touch, and some features are only available for the 32 and 64 GB third generation iPod Touch released in September 2009 and the fourth generation iPod Touch released in 2010.

In June 2011, iOS 5, the fifth major release of iOS software, was announced at Apple's WWDC 2011, which added notification, messaging and reminder features. On October 4, 2011 at Apple's "Let's Talk iPhone" event iOS 5 and the iPhone 4S were announced to the public with many new features such as Siri, iMessage and wireless upgrades; this software upgrade was released on October 12, 2011. No new iPod Touch specific changes were announced at that time beyond a price drop and availability in black and white.

iOS 6, which was released on September 19, 2012 to the fourth and fifth generation iPod Touch and other compatible iOS devices, contains 200 new features including Passbook, Facebook integration and Apple Maps. On certain iPod Touch devices, the ability to take panoramic photos was added, a feature shared with the iPhone 4S and iPhone 5.

Comparison to the iPhone

The iPod Touch is a media player and personal assistant, not a smartphone. It is generally similar to the iPhone and shares almost the same hardware and runs the same iOS operating system. The iPod Touch lacks some of the iPhone's features and associated apps, including the built-in compass. Older models also lacked speakers, microphones, and cameras. Since it doesn't need cellular components, the iPod Touch is slimmer and lighter than the iPhone. Steve Jobs once referred to the iPod Touch as "training wheels for the iPhone".

Another major difference is the quality of the back camera compared to the iPhone. While the iPod Touch, like the iPhone, allows for HD video recording, the iPhone's camera still delivers higher quality photos. Until the fifth generation, the iPod Touch camera lacked a flash for low-light photography. Until the release of the iPod Touch 4th generation the sleep/wake button was on the opposite side.

Requirements

• iTunes 10 or later (iTunes 10.5 for iOS 5.0+)
• Mac OS 10.5 or later (10.5.8 for iOS 5.0+)
• Windows XP Home or Professional with Service Pack 3 or later (Vista or later to use iCloud)

Setup and synchronization

For iPod Touch units bought before October 12, 2011, users must own a Mac or PC computer to be able to use the iPod. Users then must install iTunes and connect the iPod through a USB port. The iPod will then be set up in iTunes. New iPods bought after October 12, 2011 have iOS 5.0 preloaded, and allow activation wirelessly, without the need of a PC or Mac.

Earlier iPod Touch units must be plugged into a computer to be synced. This will charge the iPod Touch and sync the music library, videos, pictures and back up data. iOS 5 enables the user to do all this from the device and send it to the iCloud service. It is not manageable by Mac OS X 10.4 Tiger.

Battery charging

Starting with the second generation, iPod Touch can only be charged from the 5 V pin of the dock connector while most prior iPod models (including the original iPod Touch) could also be charged from the 12 V pin for FireWire power. This change dropped support for charging in vehicles equipped with a FireWire-based iPod connection. Most aftermarket manufacturers of such equipment offer cables and/or adapters which convert the vehicle's 12 V to 5 V.

Apple Lightning connector

The fifth generation iPod Touch and iPhone 5 feature a new dock connector, named "Lightning," which replaces the Apple Dock connector on older iPhone / iPad / iPod models. The Apple Lightning connector has eight pins and all signaling is digital. This new connector is smaller than the previous one allowing the iPhone 5 slimmer form factor. Apple Lightning cables have duplicate pins on two sides of each plug so it will insert in either direction. Various accessories will be available to convert the Apple Lightning connector to the older Apple Dock connector or USB, although not all old accessories will work, as not all signals are available.

Purchasing content

To purchase content on the iPod Touch, the user must create an Apple ID or have an existing account. With this account one may download music and videos from the iTunes Store, apps from the App Store, or books from the iBookstore. An Apple ID account created without a credit card can be used to get free content, and gift cards can be bought to pay for apps instead of using credit cards.

Third-party applications

The only official way to obtain third-party applications for the iPod Touch is Apple's App Store, which is a branch of iTunes Store. The App Store application, available in all versions of iOS from 2.0 onwards, allows users to browse and download applications from a single online repository (hosted by Apple) with the iTunes Store. To develop such software, a software development kit (SDK) was officially announced on March 6, 2008, at an Apple Town Hall meeting. The iOS SDK allows making 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 money earned. Apple retains 30% of the sale price with no minimum fixed fee.

Hacks

A month after the first iPod Touch was released in September 2007, hackers released JailbreakMe 1.0 (also called "AppSnapp") to jailbreak iPhone OS 1.1.1 on the iPhone and iPod Touch, enabling users to install third-party programs on their devices (otherwise unavailable since the App Store was not part of iOS yet). These third-party programs could use additional functionality not supported by Apple, such as enabling multitasking, applying themes to the home screen, or enabling a battery percentage indicator. As of December 2012, each version of iOS prior to iOS 6 on iPod Touches can be jailbroken, from 1.1.1 to 5.1.1 (with a tethered jailbreak for versions 4.3.4, 4.3.5, 5.0 and 5.1) and iOS 6 on iPod touch 4 has a tethered jailbreak for 6.0 and 6.0.1, using various tools including PwnageTool, redsn0w and Absinthe(see iOS jailbreaking for details). Apple's warranty statement implies that an iPod Touch after jailbreaking or other modification made by unofficial means is not covered by Apple's warranty. Jailbreaking is a violation of the Terms and Conditions for using iOS. The jailbreaking process is easily undone by performing a restore through iTunes.
