When you are checking out you can purchase a Gelaskins protector for like $7. This comes with a short one to fit the screen perfectly between your top and bottom skin. And it comes with a full front protector if you don't want the top and bottom skin.
I don't really like the protector much, it has a colored background look to it when you view it at an angle when it is bright. And it gets finger prints quickly. But it protects the screen so it gets the job done.
But if you choose to get another protector instead of the ones sold by Gelaskins you can always attempt to cut it down to size
