Can I change my iPhone color from black to white for free?

I have the black iPhone and I really want the white iPhone. I got the black iPhone because it seemed like it wouldn't get as dirty but I have been reading that it gets dirtier easier than the white one. I have Verizon and I was wondering if they would let me do a swap (with the exact phone, no difference except color) with no cost or a small fee. Also if they let me do this, would I have to start a new plan? My plan is over in September and I do not want to get a new plan.

The store probably won't do a swap, but if you have a bottle of white-out handy I'm sure you could pay someone to get you a white iPhone.

Why would you want to potentially start a new plan NOW? Just wait till September and get a white iPhone. Easy

You can buy colored screen protectors to make your iPhone look a different color. I have a bluish green one, and when I get tired of it, all I have to do is just peel it off, and it's really cheap too. I found a white one for the iPhone 5 on Amazon that's only $8.57.It's only for the front screen though.http://www.amazon.com/Mercury-Finish-Screen-Protector-iPhone/dp/B00A6HSMBQ/
