Mobile tourism service applications can be developed and successfully deployed with the rapid developments in mobile phones, communication technologies and tourism. In many situations, when travelers visit a country for a special event or just as travelers, it is obvious that they want to utilize the time and resources efficiently to enjoy the events and visit many places as possible. To achieve this, a traveler needs variety of information to make decisions and travel plans. Traditionally, this means purchasing tour guide books about a county or a city that refer them. At the same time, the 29th Olympic game is coming to the oldest civilized country China in 2008. The goal of our mobile service is to provide needed tourist information of the host country as well as event specific information. In the case of traveling for a special event, it is crucial to be informed about the last minute changes in the schedules. Our implementation tries to address these issues as much as possible.
