I waited on line at verizon the morning of launch day only to find out that space grey was the only option (was planning on getting gold ) I didnt want to risk getting out of line and looking elsewhere so i just went with grey. Overall i'm happy with my decision but wondering if the white face would look better with ios7. Also, my last phone (iphone 4s) had a white face and i feel like the black face attracts so much smudge and fingerprints. Im thinking about swapping it out for a silver once there in stock. How much would it be to swap colors at apple store?
