Download the iOS air projector app for free (was $5)

Here is an app that will enable you to project photos and PDFs directly over Wifi without having to use a VGA dongle. It is called Air projector. It project your documents wirelessly from your iPod touch or iPhone to a browser on the same network. You don't need any additional software to make it work. Once installed on your device, you just have to launch it and that is it. As you flip through your handset, this automatically reflects on the remote display. To show a laser pointer you can tap and hold on an image. This tool is great for your PowerPoint presentations. It is available for free as at now on the iTunes store. It may go back to its normal price of $5 later on.
