Can i trade my white iphone 4 for a black one at verizon store?

The white iphone 4 is in perfect condition, my scratches, marks, dents nothing. I wanted the black one but they were out of stock and i was stuck with the white one but if i go into verizon store, will they let me trade it?
-i still have the original box
-i got the phone i would say about, 4-5 weeks ago (i had it replaced due to a broken screen)
-i have warranty on it

No they won't
