so don't be cheap and not buy a case or screen protector.
No it's Apple's version of the scratch and win game. Take an chance and scratch your black iPhone 4 for a chance of it being a white one underneath!
Do you know what did it? Big difference if it was scratched by a diamond ring versus your car keys, for example.
Especially with that beautiful screen. I've never understood why people would ruin the quality of the display.I'll never stick a screen protector on an iPhone.
Just because I don't buy a case or screen protector doesn't mean I'm cheap. I have never used either for any of my iPhones and I've never gotten a scratch because I don't drop my phone. I think the cases make it look ugly and bulky, so I just don't use them.
First of all, good job Engadget to post that photo and not give any details about what scratched it.
Second, I am never putting a case or screen protector on my iPhone.
My iPhone 3G never had a case, and was in and out of my pants pocket probably 20 times a day for over a year. When I sold it this week, it didn't have a single scratch on the screen, and only a few minor scratches on the back.
It IS possible to take care of your phone, you know.
