I never returned or exchanged any Apple product. What would be the best way to exchange my opened White 64gb iPad 4 for a Black one? I just got it yesterday so I'm still in the return window. So should I just take it to the store and they will give my the Black one? It shows as in stock. Or should I return the White one and buy the Black one online and select in store pickup. What would you all do? How "nice" is Apple about this stuff? Again I never did it. thanks!!
