Bored with the look of your iPhone 4? Why not stick a stainless steel back plate with an artistic photochemically etched design on the back of your iPhone 4 made by Luxe Plates. You can choose from various designs made by different artists or even upload your own design to make a custom Luxe Plate. These plates are currently available only for the iPhone 4 and will run you $22.95, and $35.95 if you feel more creative. If stainless steel is a bit much for your taste, then you can always go with good old wood.
