Honest question: Will you take different actions depending on the answer? For example, if you're just curious don't take it off and don't worry about it. If you want to try and have it repaired with AppleCare I would wait until your AppleCare is about to expire or until another issue (possibly) develops. If it's for resale value I wouldn't worry about it and simply mention the screen protector has a scratch.I noticed I have some on my 4s. Is there anyway to tell of they're just in the screen protector or if they made it all the way through to the 4s outside of peeling it off?
