This year, to help attendees keep their fest to-do lists in order (and save them the trouble of lugging around printed schedules), the 2010 Sundance Film Festival is debuting their first official iPhone app. Designed by Vancouver-based mobile marketing company QuickMobile, who pulled it together with the assistance of a grant from Telefilm Canada, the application offers users a comprehensive list of screening schedules and events, as well as maps, updated press articles and Twitter and Facebook links.
