No current plans to upgrade, but if I did, I'd go with black again. I don't like the way white iPhones look. I'd love to have a purple iPhone actually.
All of my current iOS devices are black so I'm getting black lol. But I put an Otterbox case on my iPhone so it really doesn't matter what color it is.
Not upgrading since I just got the 4s in June. But ifI were I would choose the white. I love white iPhones and a white i5 would match my other devices.
