Canopy shows off two iPhone 4 cases at CES. The first one, Jumba, adds tripod threading, making it easy to tripod mount your iPhone 4 at virtually any angle.

The second iPhone 4 case, Kapok, converts your iPhone to a point-and-shoot camera. By combining an iPhone app with the Kapok case, you get two embedded buttons with better digital camera control for the iPhone 4 camera.

Canopy offers an open SDK, so the buttons are available for use by other apps too.
