If you're looking to view or save documents on your iPhone, you're out of luck without an application. Enter Documents to Go. The program has the ability to sync and view Microsoft Office files, PDFs and more to your phone or iPod touch, making it a convenient storage place for syllabi, class notes and more. And though we'd be loath to write much more than a text message on the iPhone, on Documents to Go you can create and format Microsoft Word documents as well. (Documents to Go, $4.99)
