Edge is at Samsung for Signal Issues - Warranty Claim

So, my phone is in the hands of technicians with Samsung over signal issues.. Most likely there's nothing wrong, but I figured; free claim/support, why not? I've been keeping track which I think is pretty informative however the most recent entry is troubling.. I don't know if they're referring to new or old scratches.. I knew there were a couple very small scratches on it but nothing at all serious.. am I just being paranoid?
