Hi all, I'm considering buying one of the "New in Box" iPhones off of eBay but I have a couple of concerns. According to the sales rep at AT&T buying one off of eBay is a really bad idea because when you buy an iPhone you have to sign up for a contract or something at the store. I realize you activate the phone at home on the computer, so this really confused me. I was wondering if anyone could write a quick note about what happened when they bought the iPhone at an AT&T store or an Apple retail store: Did you simply buy the phone w/out giving any information, take it home and sign up for a service contract? OR Did you give them a lot of information, take it home, then activate it? Is the SIM card included in the sealed box when you buy it? Any help would be nice as the phones are going for less than $600 w/ shipping included rather often on eBay. I'm just worried about buying an iPhone that I can't activate. Of course, I would be buying a "new in box" and "factory sealed" and definitely not a used one that already has a contract. Thanks for any help!
