Apple unveiled the 4th generation iPod Touch on September 1, 2010. It features a front-facing camera for FaceTime, the iPhone 4's Retina display without an IPS screen, support for recording 720p video and 960 x 720 still photos via a back camera, Apple's A4 chip, a built-in microphone, and a 3-axis gyroscope. For the appearance note also that the blank display has a significantly darker and more glossy tint than the prior models, as the higher pixel density absorbs a wider spectrum, darkening the reflection. On October 12, 2011, the iPod Touch 4th-generation began shipping with iOS 5.0 pre-installed for PC-free activation. Also, an additional color option, white, was made available. Before you can use any of the iPod touch features, you must use iTunes to set up and register iPod touch, and to create an iTunes Store account (if you don't already have one). 1. Download and install the latest version of iTunes. 2. Connect iPod touch to a USB 2.0 port on your Mac or PC using the included cable. The USB port on most keyboards doesn't provide enough power. Unless your keyboard has a high-powered USB 2.0 port, you must connect iPod touch to a USB 2.0 port on your computer. 3. Follow the onscreen instructions in iTunes to set up iPod touch and sync your music, video, photos, and other content. Related article: convert flv to mp4 mac | put youtube videos on ipod
