splash Masque Clear Screen Protector for iPhone 4 4G  4S AT&T and Verizon (3-Pack + 2 Bonus Back Films)
This is an average product at a premium price (when shipping is factored in).  I selected this brand because I prefer a front screen protector that has a separate cut out for the camera, as opposed to the single elongated oval cut out on many other brands.  However, the cut out hole for the camera is way too large, in my opinion, and looks akward.  Based on overall quality and fit and finish, I recommend the PhoneDevil product.
