Can I switch my black iPhone 5 for a white one?

I bought a black iPhone 5 early October. Well I noticed it has connection problems where my phone will randomly go to "No Service" at least 2-3x a day. It is frustrating! Also I noticed today that my camera lens has a small dust particle behind it and it shows in all my pictures. I cleaned off the lens as well as I could but it is still there. My plan is to take the iPhone to an Apple Store and show them these issues, and most likely they will grab a new phone from the back and exchange it. My question is if they go in the back to grab another, could I ask before hand if I can keep the same model and 16gb but change the color to white? It seems reasonable. It's just a color right?
