iPhones were a type of mobile phone on 21st century Earth. Patricia Menzies mentioned them to the Sixth Doctor. (AUDIO: The Crimes of Thomas Brewster)

Clara Oswald had an iPhone. (TV: The Time of the Doctor, et al.) During the Twelfth Doctor's imprisonment in the Prison, Clara's iPhone was incinerated. (PROSE: The Blood Cell) Clara obtained another and, in her form, Bonnie used the phone to record video and send and receive video calls, while Clara, connected to Bonnie's mind, sent text messages to the Twelfth Doctor without Bonnie realising. (TV: The Zygon Inversion)

The members of the Coal Hill Year 8 Gifted and Talented Group all had iPhones. In the 21st century, when Earth had become overrun with trees, they used Samson's to take selfies. (TV: In the Forest of the Night)

The Twelfth Doctor also had an iPhone, which he used to call Clara and Bonnie, in her form, multiple times. (TV: The Zygon Invasion, The Zygon Inversion)

Courtney Woods had an iPhone as well, and she used it to post pictures of the Twelfth Doctor on the Moon onto Tumblr in the year 2049. Clara Oswald noted that to the Doctor.

Other similarly named devices from that era included the iPad and the iPod. (TV: Dark Water, A Day in the Death)
