The iPhone version of HamExam.org is optimized to work on iPhones and iPod Touches. It may work on other devices, as well, but it hasn't been extensively tested. When time allows I will make a generic mobile site that is compatible with Windows Mobile and other platforms.

If you add a bookmark to this site to your home screen, it will behave like a regular app (except that it requires internet connectivity) and will not have the usual Safari buttons.
