I saw this ad on gumtree about a brand new sealed iphone 4 factory unlocked for £400. I spoke to the guy on the phone and arranged to meet the following the day in New Malden. Next day we met at Mcdonald in New Malden. The guys in his early twenties, had a rather middle eastern look (then again I could be mistaken here). At mcdonald, on the spot before paying him cash, I called Apple store white city to check that the phone is not registered, not reported stolen and indeed factory unlocked. Everything checked out and I registered it with my name, mobile number and email on the phone. We shook hands and he even directed me to the nearest Three store in order to get a microsim, something which I didn't know but hey that was nice of him. He also told me how iphone 4 has problems with its antenna and all...that I had already known. Before we parted ways, I broke the seal and checked that there was nothing funny inside - that also checked out. Anyway, went to Three store, picked up a microsim, went home and waited up to 24h to activate it in order to activate my new iphone (it's like double activation arghhhh!!!). Long story short, I decided to use a normal virgin sim, cut it down to micro size and voila! I activated my iphone 4! I even made a few calls with that sim, browsed the net. 24h later, tried the microsim from Three, itunes gave me something like "this sim card doesn't seem to be supported blah blah blah..." tried an o2 microsim, same thing. Retried virgin sim and called their free number 789, no longer worked!!! Got bck in touch with the guy who sold me the phone, he was still cool and apologised. He said then he spoke with orange from whom he ordered the phone, they said the phone was supposed to work only with his sim and any other will get the phone blocked. Indeed i suspected that my iphone was blocked, but Apple didn't seem to notice that the many times I spoke with them on the phone, gave them the serial number and the IMEI. The phone was not reported stolen or anything. Now the guy agreed to refund me. He would send the phone back to orange and they would replace it with one that would accept every sim. He even agreed to refund my travel expenses. He told me that he has no debit or credit card, he is going to pay me by cheque. He will even bring his ID when we meet up so that I have peice of mind. Before we met, I spoke with London Metropolitan Police and there was pretty much nothing they could do, they just told me not to accuse someone until fraud is committed so I should meet up with the guy and accept the cheque. I shouldn't worry about whether or not the cheque is false at this stage. I even went to my bank and told them the situation I was in, if they cheque was a forgery and/or bounced, I wouldn't be penalized or anything, they said, no I won't, the bank will just write to me and inform me what had happened with the cheque. So we met up today, he again apologised and didn't get why Orange had blocked the phone. We sat in a coffee shop, we chatted and finally I showed him his iphone in still brand new condition. He took out his cheque book, signed a cheque for me. I checked his signature with his provisional driving licence. Checked his picture against his provisional licence. I even took a photo of him with my phone, he laughed. I took a picture of his cheque together with his driver's licence, I made him write on a piece of paper and sign that he had sold me an iphone 4 serial number [xxx] on [date] to me [full name]. He now is refunding me £400 paid by cheque. I finally went to my bank, deposited the cheque and now I am waiting. All these measures I took was for my peace of mind and and yet the guy was all laid back and cool about it. Now, given his handling of the situation, does this guy sound like a scammer or he is genuine? with appearance, I couldn't see anything wrong with him. I'm still a little shaken for the fact that I got cheques instead when I bought the iphone with cash. I told the guy I still want the iphone 4 and he said, if that's what I want, he would get back to me as soon as he gets the replacement and I will pay him back his money (obviously from his cheque). Anybody can share anything about this situation? any post here or to my email would really be appreciated. Thanks.
