Users of this book will be able to quickly and efficiently build I-Mode pages using any desired text editor. Following examples and instructions based on the authors' successful experiences, developers will create or convert images from other platforms, create animations and sound files, and develop dynamic database driven I-Mode applications and Web sites using common scripting languages such as Perl, PHP, and Java. They will also understand the relationship between I-Mode and other wireless technologies, and the unique business model of I-Mode. An overview of several "killer applications" that have fueled I-Mode's success will further prepare the reader to create applications that take full advantage of the features of small-screen devices.
