Nokia Lumia 920 on AT&T Functionality Question / screen timeout = never option

Hi, for those who have the 920 on AT&T now, please answer me this: If you go to settings / lock+wallpaper / Screen Times Out After Do you have the option to choose 'never' in addition to the usual 30 sec, 1 min, 3 min, and 5 min.? AT&T or Samsung chose to disable this 'never' option on my 7.5 Samsung Focus S. I'd like to be able to keep the phone displaying while playing music driving on my commute so I can quickly check the meta-data and not have to tap it every 5 mins. to keep awake or re-open the phone. Thanks -
