Can you pick the color of your iphone when you get an upgrade?

I'm getting the iphone 5 for my upgrade in 2 weeks and i wanted to know if they will let me pick the color

Yes, you can only not pick your color when you are getting an exchange through AppleCare. Their policy is to only exchange for the same item ergo the same color.

Upgrade since you are paying the $199,$299, or $399.It's up to you. Of course you know the options are the black/brushed aluminum, and white/silver
