So I've just pulled my iPad out of the Apple case ready to box it up and post to its new owner... has anyone else found they're really tight to pull out? Anyway I gripped it pretty tightly and was able to wiggle it now but now when you squeeze one of the sides of the iPad it makes a squeaking sound

I have NEVER noticed this until today... I had the iPad in and out a couple of times when I was photographing it in the different cases before I put it on eBay and would definitely noticed it then if it existed.
This iPad has to go out tomorrow... what to do what to do? Refund the guy his money and take it to the Apple store? It's under warranty until January. This is my first eBay sale and I don't want negative feedback
