Ok, the google thing is kinda funny 🙂
Anyways, I'd recommend going for a slightly more expensive skin thing such as the Invisible Shield by Zagg or the Bodyguardz film. These cover both the front and back if you want, and they are much tougher than the cheap screen protectors. Plus, if applied properly, they don't leave smudges or air bubbles cause of the liquid application. Believe me, I've tried both for my iPhone, and I wouldn't bother with the cheap static-cling screen protectors.
