BlitzCheck from Wombat Mobile allows you too look up trivial information form the web more easily. It is a J2ME midlet which queries a search engine based on a query you enter. It is aimed at retrieving trivial data (such as who sung certain lyrics). Should be good for those late night pub quizzes, and is a good example of how to implement a useful mobile service. The author also has an interesting blog where you can see recent developments (such as the use of the Yahoo Search API) and there is also an interesting concept traffic / map J2ME midlet.
