This video shows us how to do a screen cast directly from an iPhone or an iPod touch in the Mac. One thing to keep in mind is that this can only be done on a jailbroken iPod. The first thing to do is to download and install the application from Cydia called Screen splitter. After downloading screen splitter launch the application and go into Safari and go to Bonjour and click on your iPod. Once you've down that you should see your iPhone displaying on your Mac. From here you'll need screen capture software to capture what you're doing on the iPhone on the Mac. Following these instructions you'll be able to screen cast directly from iPhone or iPod touch.
