First of all, this is my first ever Apple product. I'm buying an used iPhone 3GS 32GB from eBay. The seller has two phones for sale - black and white. The black one comes with a screen protector while the white one doesn't. Also the black one comes with a case which is not included with the white one. Now, I find small spots (something like faded) on the black one while the white one literally has no scratches (both front and back). I feel like going for the white one since it has no scratches and looks better than the white one but it lacks screen protector. I want to know if screen protector is really necessary or not. Also I'm thinking of using Apple socks when I keep the phone in my pocket instead of cases as I feel cases ruin the awesome look of naked iPhone. What do you guys say? Black one - http://cgi.ebay.com/Apple-iPhone-3GS-Black-32GB-AT-T-iOS-4-1-/330501178931?pt=Cell_Phones&hash=item4cf367c633 White one - http://cgi.ebay.com/Apple-iPhone-3GS-White-32GB-Very-Good-Condition-/330505934188?pt=Cell_Phones&hash=item4cf3b0556c The black one includes more accessories than the white one but thats not a biggie..
