The fourth generation iPod Touch (marketed as "the new iPod touch", and colloquially known as the iPod Touch 4G, iPod Touch 4, or iPod 4) is a multi-touch mobile device designed and marketed by Apple Inc. with a touchscreen-based user interface. The successor to the 3rd-generation iPod Touch, it was unveiled at Apple's media event on September 1, 2010, and was released on September 12, 2010. It is compatible with up to iOS 6.1.6, which was released on February 21, 2014.

The fourth-generation iPod Touch was the first iPod to offer front and rear facing cameras. It is a slimmer, lighter model than its predecessors and the iPhone 4, and introduces a Retina Display. Other improvements include support for recording 720p video via the rear camera, Apple's A4 chip (the same chip used in the iPad (1st generation), and iPhone 4).
