DS Import Repair Question

[NOIR]

Today I had my DS in my pocket and my friend wanted me to go Picto Chat and I opened it up and the screen had a cracked hole or something on the top screen. When off it is all rainbow-ish. The top screen still works, but the huge crack. I also just got it on Monday and I am worried that Nintendo won't let me to send it in for repair because it is a import.

Does anyone know anything that could help me? Please!
