There are many tools you can use that will make your life easier in mobile web development, many more than we could ever cover in this book. We will first look at a wonderful tool that will make your life easier when it comes to styling your jQuery Mobile applications: jQuery ThemeRoller. Next up we will take a more in-depth look at the IDE Aptana Studio and how we can begin to harness the power of this powerful, yet free, application. Finally, we will look at Screenfly and how we can use it to test the responsiveness of our mobile web applications and how the site can look and behave on different devices and browsers.
