Siri
Siri was originally released as a stand-alone application for the iOS operating system in February 2010, and at the time, the developers were also intending to release Siri for Android and BlackBerry devices. Two months later, Apple acquired Siri. On October 4, 2011, Apple introduced the iPhone 4S with a beta version of Siri. After the announcement, Apple removed the existing standalone Siri app from App Store. "TechCrunch" wrote that, despite the Siri app's support for iPhone 4, its removal from App Store might also have had a financial aspect for the company, in providing an incentive for customers to upgrade devices. Third-party developer Steven Troughton-Smith, however, managed to port Siri to iPhone 4, though without being able to communicate with Apple's servers. A few days later, Troughton-Smith, working with an anonymous person nicknamed "Chpwn", managed to fully hack Siri, enabling its full functionalities on iPhone 4 and iPod Touch devices. Additionally, developers were also able to successfully create and distribute legal ports of Siri to any device capable of running iOS 5, though a proxy server was required for Apple server interaction.
Over the years, Apple has expanded the line of officially supported products, including newer iPhone models, as well as iPad support in June 2012, iPod Touch support in September 2012, Apple TV support, and the stand-alone Siri Remote, in September 2015, Mac and AirPods support in September 2016, and HomePod support in February 2018.
Sour Milk Sea
The "Sour Milk Sea" single was issued on 26 August 1968 in America (as Apple 1802) and 6 September in Britain (as Apple 3). Along with "Hey Jude" by the Beatles, Mary Hopkin's "Those Were the Days" and the Black Dyke Mills Band's "Thingumybob", it was one of Apple's "Our First Four" singles, marking the official launch of the label. The four releases took place on the same day in the United States but were spread out over two weeks in the UK. Apple staged a lavish promotional campaign for the launch, led by Derek Taylor, whom Harrison had invited to help run the Beatles' new enterprise. In advance of the release date, the company declared 11–18 August to be "National Apple Week" and sent gift-wrapped boxes of the four records to Queen Elizabeth II and other members of the royal family, and to the British prime minister. In an interview to help promote "Sour Milk Sea", Harrison said that the song's message would "[go] above the heads of some people", but it was a "very good record" and indicative of his and Lomax's decision to put artistic merit before commercial considerations. Lomax carried out radio promotion for the single in November, while he and Harrison were in the US recording further material for Lomax's album, "Is This What You Want?"
