you can get a nice bumper form Amaozn,New iPhone 5 Bumper Case Black Transparent TPU Clear, Better than the black plastic one I bought from another seller that I actually had to dremel to get the lightning cable in flush. This one has the holes cut correctly and has metal buttons similar to Apples legacy bumpers. Great deal for 10 bucks!
