Due to the whole pre-order fiasco, AT&T had two of my orders for iPhones go through. As a result, I received TWO of the new iPhone 4s. I was charged the subsidized price for both (one charge went to my debit card, the other to my credit card). I activated the first phone I got and it is now tied to my line. I called AT&T about the second phone but, ironically, the call was dropped before I could get much information. I could go through the trouble to return the phone and get one of the charges removed, or I was thinking I could sell it on eBay for profit. Question is, what do I need to do/say to safely sell it on eBay? Do I need to remove the SIM card? Or should I not open the box? My line is active with one of the new phones, so I don't think I'll be charged any fees for not activating the second phone. It the phone tied to JUST my account or could anyone activate it with AT&T? If I don't remove the SIM and someone else does activate it, does that cancel my service? I just want to make sure I don't screw myself over here. They're selling for almost $800 on eBay, so I'd be stupid not to go that route if I can. Thanks!
