I recently broke my black iPhone 4. Fortunately, I have insurance so I was able to fill out a claim and my new iPhone is on its way. I should receive it on the 27th or 28th. Since the white iPhone is rumored to be released this week, do you think I could take my brand new black iPhone 4 into an Apple Store and exchange it for a white version? I'm not sure what the return policy is, especially since I didn't actually buy it from the store.
