I googled it and most people seem to think its not, but I am just asking because the other day I went into O2 and bought an iPhone, no questioned asked, but had to pay by credit card. Today I went to a different O2 shop to buy another iPhone. They once again wouldn't let me pay by cash, so I paid by card, a different one than before. this time though, the guy asked me all sorts of questions, including my address, phone number, post code, email address, and who the phone would be registered to. I was planning on selling it on eBay, so I said it was a gift for a friend. Am I doing anything naughty? I haven't unwrapped the second iPhone yet, so I could just return it. Thanks.
