This highly ornate case isn’t going to be everyone’s taste, but I think it’s beautiful. The Nouveau Art iPhone 4/4S case from Ion is a polycarbonate snap-on back cover. It’s available in iridium-coated silver or goldtone, so it doesn’t interfere with the signal strength. The camera and all ports and controls are open and accessible. The Nouveau Art cover comes with an anti-glare, moire-free screen protector. It’s $35.99 from Ion.
