Does anyone know of one that can go down more than just a few feet, and allows you to use the camera? I've been searching like crazy and can't find one. I find it hard to believe, with the image and especially video quality on the iPhone 4, that no one has made one yet. Yeah I know it's not a real camera. I personally have a Canon 40D with a housing, strobes, etc. But the quality on the new iPhone is definitely good enough for short clips to post on the web, underwater inspections on boats, etc. And it will fit in a pocket, unlike a real camera. The HD video quality is pretty damn good, even at full screen, when you consider it was shot with a phone. Unfortunately the cases for iPhone seem to fall into 3 categories. Bag style, which for the price actually work well. You can use all the phone's features, but only to 15-20'. Big bulky things that are barely water resistant, and seem to have horrible reviews from most users. And iDive which seems to be really rugged, and rated to 300'! But won't let you access anything except the iPod controls.
