What happens when you change the color of your iPhone?

I recently changed my iPhone color from white to black because of some reasons. Last week I have dropped my iPhone and it cracked the front screen. My back plate is plastic and I'm not happy with the results I had when I got it changed. I have Verizons extended warranty for it and I never used it. Do you think they could replace it to the same white one I had before? I really need your answers please help!

I don't think they'd replace it. I recommend buying a high quality, coloured panel for your phone. Verji sells them and they're located in Sydney which makes them a lot more reliable than buying one from China (well in my opinion, anyway)
