WaterField Designs has announced the iPhone 4 Smart Case (http://www.sfbags.com/products/iphonesmartcase/iphonesmartcase.htm) with new colors and naturally tanned, distressed, leather sides. Pricing ranges from US$39 to $45.

Three carry-options include a svelte Slip style, a clip style for attaching to belts or other garments, and a Flap style for attaching to bag straps. The Smart Case comes in black, copper, pine, green, flame or pearl flavors.

WaterField also offers the iPhone Travel Case ($35 to $37), which is designed to keep the iPhone 4 and its accessories organized and tangle-free. Custom-sized, padded interior compartments keep items separated. Self-locking zippers ensure the contents don’t spill out accidentally. All three sizes (small, medium and large) purportedly maintain their thin and compact shape, even when fully packed.
