Mr. Mobile takes a look at three iPhone accessories that he goes as far as saying are real must-haves for iPhone owners. First, we look at an extended life battery pack that doubles the battery life of your iPhone 3G. Next we see a simple, non-electronic gizmo that improves the experience of watching movies on your iPhone for under $10. Finally, we see an iPhone case with a kick stand, perfect for watching movies on the plane without having to hold your iPhone.
