I love the swivel monitor on my Canon 60D but as I am planning to upgrade to a camera with a fixed screen I am also looking into some small external monitors with swivel capabilities. I saw some interesting options from Sony and Swivi but they are all around $350-$400.
Is there any way I can hookup my existing iPhone 4 and connect it with a Canon DSLR camera HDMI output. I Don't need to control the camera options but I would like the be able to see the live view on the phone.
Edit: What I am looking for is a setup similar to one shown in THIS video but for using iPhone
