The Man in Grey's smartphone
From Jenny Everywhere Wiki
The 925th Universe's Man in Grey owned a smartphone by the time of his first meeting with Bunny Everyhare. He was playing a “particularly predatory” Kyujudo game on it when Jenny Over-There came to him for help about the mysterious call from Bonham. The two later used the smartphone to call Kyujudo and Dibbsy's lawyers to take care of Bonham. (PROSE: Who Laws the Lawyers?)
