This new series of full-body clear iPhone 3G and 3GS film protectors -- Art Shield ($28) -- adds a new twist to prior designs we've seen: United SGP has added decorative, clean graphics to the back film, and continues to include two pieces of clear front film in each package, along with applicator spray and a squeegee. The company offers downloadable unlock screen wallpaper to match the designs of the Art Shield stickers, as well.
