Seriously? You are overreacting. No buyer is going to refuse your phone next year because of that. The phone isn't a water-balloon, it can be touched and set down without a case. Goodness, I was expecting gashes, thats nothing.
To those saying he should have raised hell, you must be kidding me. Thats like screaming at a valet for driving over an ant-hill when going to park your car.
Wow. Just wow.
Are you kidding me? Please say yes.... waiting... no, you are serious.. oh god.
The resale value for a year old phone is what, $350? So you mean to tell him due to those hardly noticeable scratches his phone is now worth $250? Or even $300? Oh my god, this really is too funny. Clearly (CLEARLY (CLEARLY)) you have never tried selling an iPhone before. You can get full price for them even if they have small scratches all over the back and chrome, people don't really care. The fact that you are devaluing the product by that much shows you clearly have NO idea what you are talking about.
Those tiny marks do NOT warrant a replacement, quit babying your stuff so much. And yes, I own a 3G S but I don't treat it as obnoxiously as some of you people clearly do.
