Yahoo, which is doing a lot right now to improve its mobile search, is adding Yahoo Answers and Wikipedia content to its oneSearch results. Yahoo has also launched mobile flight information search today, which has a few shortcode options like "UA 90" for United Airlines 90, that will give you an overview of information for that particular flight. The hope is to boost Yahoo mobile search and give the types of resources that hopefully give instant answers instead of a page with links you'll have to sift through.
