The iPod touch is an Internet-equipped multimedia device designed and built by Apple. It's capable of purchasing, downloading and running a host of games and applications that significantly expand its functionality. The device comes equipped with an application that allows access to the iTunes App Store directly from the iPod touch, where software can be downloaded via a Wi-Fi connection and automatically installed.
By installing Apple's iTunes software on a computer you can gain access to the App Store where the iPod's digital content is listed. iTunes should be signed into the same Apple account as the iPod you intend to install the games on. Games and applications can then be purchased through iTunes on the computer, and installed onto the iPod touch by synchronizing it with the computer using its USB cable. Any compatible content purchased through the computer will automatically be added to the iPod touch.
The iPod touch has an App Store application built into its firmware, alongside an iTunes application. By launching the App Store app, you can browse through all the available software for the device. Any purchased content is then downloaded and automatically installed onto the iPod touch. A backup of the installed games is made automatically on the computer when the device is synchronized with iTunes. You must be connected to the Internet via Wi-Fi to use the App Store on the iPod touch.
The App Store is not directly available through a Web browser. The only way to browse the App Store is using the iPod touch application or through iTunes on a computer. Apple provides a custom hyperlink service for linking indirectly to content listed on the App Store; following such a link will automatically launch iTunes or the App Store application. Once the App Store has loaded, it will automatically open on the relevant page so you can download and install the game or application on the iPod touch.
"Jailbreaking" is a process that unlocks the iPod touch from the App Store and allows you to install unofficial third-party games and applications. This software doesn't need to go through Apple's approval process, and many developers choose to release their games through an alternate application store called Cydia. This store is only available to jailbroken devices, and allows you to install games and software directly onto the iPod touch with a single button press. Jailbreaking is perfectly legal, though it does void the device's warranty.
