For many months, tech blogs like ours used the name iPhone Ultra to refer to Apple's rumored foldable iPhone, but the device ended up being named iPhone Duo. The name iPhone Duo was not a complete surprise. Daring Fireball's John Gruber accurately guessed that the device would be named iPhone Duo all the way back in April, and the name made the rounds again on social media last week.
