Many older devices are susceptible to jailbreaking, which circumvents these restrictions. The iPad's App Store is subject to application and content approval. The iPhone's iOS operating system (OS) was initially used for the iPad but in September 2019, its OS was switched to a fork of iOS called iPadOS that has better support for the device's hardware and its user interface is customized for the tablets' larger screens. The iPad range consists of the original iPad lineup and the flagship products iPad Mini, iPad Air, and iPad Pro. Speculation about the development, operating system, and release of the original iPad began in 2002 prior to its introduction on January 27, 2010. The iPad was conceived before the related iPhone but the iPhone was developed and released first. The iPad is a brand of iOS and iPadOS-based tablet computers that are developed by Apple Inc.
