It is not like someone who flips the phone has some sort of advantage over the average consumer. They have to get through in the pre-order process just like anyone else. Why is that anyone else's business, what they choose to do with the phone? If they get up in the wee hours of the morning to pre-order a phone, are lucky enough to get one, shell out $1200 to get it, and find some idiot on eBay willing to pay $3,500 because a) they are impatient and b) they have the disposable cash then good for the seller! I know I won't be butthurt over it. They did nothing wrong. They followed the same path everyone else did.
Edit: Shaking my head at all of the people calling these flippers scums and moral-less people. If you want a phone that badly, pre-order before they do! It is that simple. You don't have any clue what they will do with any profit they make. Maybe they will donate that profit to a charitable cause. If so, are they still scum of the earth? If I buy the last raffle ticket before you can, and I win the prize, am I scum because I didn't keep the prize but instead donated it back? And even if they keep the profit to better their family or their life, who are any of you to judge? What, because you wanted the phone but now have to wait an extra week because someone beat you to it? Quit crying.
