TUAW reports that the iPhone firmware 2.0 enables users to easily take and share screenshots of their iPhones without having to download any additional software. To take a screenshot, just hold down the home button while quickly pressing the sleep/wake button at the top of the phone. The screen will flash and an image will be saved in your Camera Roll. iPhone users can easily share screenshots via email with the share option in the Photos app.

This could be a pretty handy tool for teaching and learning, especially for university training sessions or instructional websites. iPhone screenshots might be used to demonstrate educational, social and administrative uses for the device on campus to students, faculty and staff.
