Apple’s 4th generation iPad was announced on October 23, 2012. While the iPad 4 still looks identical to 2011 iPad 2, early 2012 iPad 3, it has an Apple A6X processor, international LTE networking, and a FaceTime HD camera that combine to make it a small but welcome upgrade. Camera extended features include iSight with Five Element Lens, Hybrid IR filter, video stabilisation, face detection, ƒ/2.4 aperture.
It shipped with iOS 6.0, which provides a platform for audio-visual media, including electronic books, periodicals, films, music, computer games, presentations and web content. It can act as a hotspot with some carriers, sharing its Internet connection over Wi-Fi, Bluetooth, or USB, and also access the Apple App Store. It was announced that the iPad 4 (along with various other devices) will support iOS 9 at the Apple WWDC 2015. The iPad 4 was discontinued in the fall of 2013 and replaced by the iPad Air. However, It returned in the spring of 2014 at the price tag of $399/$529 for 16GB.
