In this video, you will learn exactly how to take pictures with your Apple iPad! Wifi or 3g model is fine, 16GB, 32GB, or 64GB models are all fine also! What you need for this to work:
An iPhone 3GS (IPHONE 3G AND IPHONE 2G WON'T WORK!)
Camera-A Application (1$): http://itunes.apple.com/us/app/camera-a/id363441925?mt=8
Camera-B Application (Free): http://itunes.apple.com/us/app/camera-b/id363442203?mt=8
With this application, you can zoom in which is cool. You can also save the picture to both your iPad and iPhone 3GS. While this doesn't take pictures with great picture quality, it could be used as a spy camera, security camera, and, of course, a way to straight out take pictures using an iPad since there's no camera.
