My cousin has the white, She thinks its pretty, But get a case, A not Tranparent case because White can Catch a Smugglers eye and Follow you to steal ur phone.
Black, because it goes with anything and is slimming *smile*. Actually, I just liked the look of the phone in black better. I had a black iPhone as well, just my preference.
I have Pebble Blue and it looks so cool. Didn't buy White as it can be dirty so easily and leave behind the stains.
Plus White looks so glossy and it appears to be feminine. So I chose Pebble Blue.
I chose blue because you can see the lines of the pebble that it's supposed to resemble. Also, it's just different than your regular black smartphones.
