ZAGG Glass Curve
ZAGG was one of the most popular screen protector companies for a long, long time, but they're also rather expensive. That said, they offer lifetime warranties, discounted upgrades for new phones, some of the best and most durable protection, precision cuts, and self-healing properties even when the screen protector itself gets scratched.
Their Glass Contour (Curve) lineup is now available and a good choice. Their typical and excellent HD clear screen protectors were the only thing available at launch, but now the Glass Curve is readily available. It's expensive, but worth it to protect that $700 smartphone. Some users claim it doesn't cover the entire front, but that's to allow owners to use a case without having it raise and get ruined.
