I would like to know this as well. I tried to cancel my order for a 32gb Black because I want the White after all the scratching issues and they shipped my order out that night instead of cancelling it. Anyone think they might be doing this on purpose? Seems fishy.
I thought most people bought a case even if it didn't have a scratching issue. It's a good idea to get one anyway for when you go to resell it some years down the line.
My iphone 4 looks as new as the day I first opened the box due to my free Speck case from antennagate. Has a nice secure grip to it and rubberized for bumps and bruises. Fits the phone like a glove. I've removed it only once in 2 years time.
BTW, a hard shell case can get scratched up too. Go with a rubberized version.
