Dave Chappell and Jon Stewart performed a 'phone free gig' at the 3Arena last night
Everyone attending was told to place their phones in a Yondr Pouch for the duration of the show.
The pouch allows phone signals to get through so you can feel your phone vibrate and if you wished to use it - the pouch could be unlocked in the lobby.
The idea behind it is to allow the audience to enjoy the show so they are not consumed with ringing, tweets and selfies.
