Over time, the artwork in GelaSkins’ collection of sticker options for Apple devices just continues to improve in quality and variety, as evidenced in the latest set of GelaSkins for iPhone 4 and iPod touch 4G ($15 each), which arrived here with updated GelaSkins for the iPad. The drill’s the same from generation to generation: GelaSkins wraps high-quality art prints around Apple’s devices using 3M adhesive material that’s capable of being removed and reused, though the iPhone 4 and iPod touch 4G skins improve upon some of their rivals by offering wrap-around side protection and matching partial face shields — top, bottom, and screen coverage are missing. As always, Lock Screen graphics to match the artwork are available from the company’s web site. Each iPhone 4 or iPod touch 4G GelaSkins package includes one set of front and back stickers and a cardboard drink coaster featuring work from a notable artist, used to keep the sticker from bending during shipment. We’re seriously more impressed every year by the art licensed by this company; see the GelaSkins for iPad First Look for more examples, including Marvel Comics art.
