I was one of those who ended up with 2 preorders. One from apple and one from AT&T. I got both today and activated the one from AT&T....can i sell my other from apple on ebay? Would it hurt that the sim card is in there? I just wanna make sure that it wouldnt effect my account. Im not to worried about if they end up charging me the difference between subsidized or not since i would obviously make enough to cover that if i sell on ebay.
