The case that launched a half-dozen clones is back for the iPhone 3G: Artwizz's SeeJacket Crystal ($30) provides front and back coverage in a largely clear plastic shell. Artwizz's once-novel front shield is a plastic screen protector that doesn't require adhesive; it's built into the case and allows touch-through use of the iPhone 3G's screen. Home button coverage is also incorporated into the new design.
