The 2011 version of the iPod touch Generation 4 was identical to previous versions of the iPod touch Generation 4, except it was also offered in white, like this example.
Although the iPod touch Generation 4 has a design similar to the iPhone 3GS, its features more closely resemble those of the iPhone 4 that sold at the same time. (The iPod touch lacked the iPhone 4 features of 3G/EDGE phone, A-GPS, and digital compass.)
The iPod touch Generation 4 included a 3.5-inch Retina Display (960×640 at 326 ppi), FaceTime video calling (using Apple ID), an integrated microphone, front-facing VGA camera, 3-axis gyroscope, and a 720p camera (lower quality than the iPhone 4). The iPod touch Generation 4 also allowed iMovie editing using the iOS version of iMovie available at the time.
The iPod touch Generation 4 used the Apple A4 processor, 256 MB of RAM, and was available with 32 or 64 GB of RAM for internal storage.
