How much does it cost to get the color of your iPhone changed?

You can't get the color of the iPhone changed. Make a decision and pick a white or black iPhone. Cases also help for changing color and making it more attractive.

My friend had a guy do it for $50 bucks plus the cost of the new screen which was $40 not sure if it was both sides. But definitely the front.
