United SGP Skin Guard for iPhone 4
United SGP's line of iPhone 4 stickers stands out from the pack for two reasons. First, unlike other companies, SGP bundles its Skin Guard for iPhone 4 ($18) with a high-quality crystal clear screen protector, so you're not just covering the device's glass back. Six different versions sent by the company include wood, leather, and carbon fiber textures that transcend the typical photographic stickers made by competitors. These are interesting options, though like most of their rivals, they do nothing to cover the iPhone 4's steel antenna frame; they'll also likely irritate the Apple logo police in Cupertino.
