The iPod touch (4th generation) (colloquially known as the iPod Touch 4G or the iPod touch 4) was the 4th generation iPod Touch by Apple Inc. Released alongside the iPhone 4, it was the first iPod to offer front and rear facing cameras. Like the iPhone 4, it used the Apple A4 chip. It fully supports iOS 4, and iOS 5, but has limited support for iOS 6 and unlike the iPhone 4, the device did not get iOS 7 due to performance issues. It was only offered in white and black. The white-colored version was added in October 2011. On October 11, 2012, Apple discontinued the 8GB and 64GB models with the release of the 32 and 64GB models of the iPod Touch 5, leaving the 16GB and the 32GB models. They were later discontinued when Apple introduced a 16GB version of its successor, the iPod Touch 5 on May 30, 2013, which was sold at the same price point as the iPod touch 4, but with a larger 4" retina display and an Apple A5 chip. On November 14, 2013, Apple issued iOS 6.1.5 for the iPod touch (4th generation) to fix FaceTime calls failing. On February 21, 2014, Apple issued iOS 6.1.6 for the iPod touch (4th generation) and iPhone 3GS to fix faulty SSL verification.
