Willow, Plusmo and Cricinfo have a free service to mobile-cast live cricket commentary of one day matches, tests and Twenty20 matches. The service works on any mobile phone by installing a client on the phone, which talks to the backend servers to refresh the live commentary ball to ball. One can set alerts for interesting events like fours, sixes, fall of wickets and most importantly"last 10 overs" where most of the one day action is centered. Now you can track your favorite team ball to ball, wherever you go. I believe they have a video version coming up too. You can download the client from

They also have launched a neat new service to bring ball by ball updates and scores to your Yahoo IM window. You can download the Yahoo IM client from Yahoo IM CricketCast plugin
