Results are formatted to be neatly displayed on the mobile screen, so there's no need to scroll side to side. Local search results now include easier-to-press "Get Directions" and click-to-call links. Maps are shown by default in the case of a single listing or accessible by the "Show map" link for multiple listings. For those of you wanting to access the classic desktop search results format, it's only a click away, with the "Classic" link near the bottom of each page.
For now, the newly formatted results pages are available only in U.S. English and for iPhone and iPod touch firmware version 2.x. Over time, we intend to make the newly formatted results pages available through other search entry points on the iPhone, on additional devices, and in more language and country combinations.
