SCREEN3 functioned by downloading data and displaying it on the phone while idle. After the user configured which
feeds or channels are of interest, feed updates were continuously and automatically
pushed to the handset via background data transfer. While viewing the small images and accompanying headlines ("bites") which scroll by on the screen, users can choose to view a snippet of the actual story ("the snack"). Users then are taken to a condensed summary version of the story or headline. At this point, if the story is deemed sufficiently interesting, users can opt to view the full story ("the meal"), causing the web browser to be launched to retrieve the appropriate web page. Modern
smartphones are capable of similar functionality via
push notifications. ==Availability==
