Functionality
The SCREEN3 feature functions by downloading headlines and displaying these to the user as part of the contents of the idle screen. After the user has configured which feeds or channels are of interest, feed updates are continuously and automatically pushed to the handset via packet data transfers which happen in the background.
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.
Billing is usually setup in such a way that users are not charged for headlines and text snippets pushed to the handset, and are instead only charged any per-byte data fees when actually viewing the full story. Rates vary by carrier, but examples include US$0.01 per kilobyte, or US$19.99 for unlimited data access.
