Apple localizes 'Trash' to 'Rubbish' in iOS 9, promotes Apple Watch with a 'rickroll'

In the Australian release of iOS 9, Apple has renamed Mail's "Trash" folder to "Rubbish." The easter egg found inside the new operating system was highlighted by AppleInsider reader Andrew.

Apple, of course, has a history of hiding small but fun details in plain sight. In various versions and applications of OS X, for example, the company has hidden the text to its iconic "here's to the crazy ones" advertisement. And since iOS 7, its Maps icon has shown the location of the company's forthcoming "spaceship" Campus 2.

In the latest inside joke by Apple, a picture of an Apple Watch support page went viral this week, as users discovered a subtle reference to the 1987 Rick Astley song "Never Gonna Give You Up."

A close look at the "Add a Friend" section of the page reveals the letters, "NE VE RG ON NA GI VE YU UP," in place of the first and last characters of the friends' name on the watch face.

A "rickroll" is an internet prank where a user expects to see legitimate content but is instead shown a video of Atsley's chart-topping hit from two decades ago.

This isn't Apple's first rick-rolling trick this year. At WWDC in June, Craig Federighi used the popular video to show audience members how to mute Safari tabs producing unwanted audio inside OS X 10.11 El Capitan.
