The 2012 London Olympics start July, 27th. There's no shortage of ways to follow the Olympics on your mobile phone. Here are my favorite sites offering schedules, predictions, results and news from the games.
BBC Olympics
Usability: 
www.bbc.co.uk/sport/mobile/olymp... (HTML5)
The BBC's mobile Olympics page uses an adaptive mobile design to work across a wide range of mobile devices. It has an extensive collection of articles with a subsection for each Olympic Sport. The BBC's sports and Olympics coverage has traditionally been top-notch so this is should be a good choice especially for in depth coverage of niche sports.

My favorite general mobile sports site, ESPN, has lots of Olympics coverage including news, schedules, results, a medal tracker, athletes bios, and background pages for the major sports, with historical records and picks for this year's top athletes. And of course there are loads of photos.
NBC Olympics

NBC has the exclusive television broadcast rights for the Olympics in the US. The network has launched dedicated web and mobile sites with extensive text, photo and video coverage of the games. NBC's site also has TV schedules and background information on the London venues, descriptions of some of the events and photos and biographies of top US competitors.
Sky Sports Olympics

British independent TV network Sky's Olympics page has Games news, complete results by day and sport as well as the entire Olympics event schedule by sport.
Google News Olymbics
Usability: www.google.com/m/news?q=olympics (xhtml-mp)
Searching Google News returns over 200,000 results for the query "Olympics". Google's especially good for finding results for a particular sport or athlete. Try queries like "London Olympics fencing"
