DO NOT USE YOR THUMBNAIL. This is not the time to be cheap. You will stress the case and crack it. If you are thinking of using a thumbnail to save a couple bucks, don't bother doing this. You are gonna void the warranty and this time they won't replace it...those tabs can catch on the LCD framing and bend the crap out of it if you aren't careful.
