Basically I purchased one from Amazon.uk, it was sold as, "used but in very good condition", for ?93, it was a good price, but unfortunately never arrived.
I do not know what happened but I got an email from Amazon saying that the phone is back to Amazon.
They did not want to send it back by tracking post, so I got the refund.
Second day, I checked the Amazon thinking that It will be back on sale with the same money, it was back, but with the price of ?169, not ?93, so I gave up.
Happy that I got it new from O2 and also cheap.
It is working perfect every since.
I would not pay, even €200 for this phone, €160 its OK. Not that is not worth, but I do not find the point paying 4-500 euros for a phone that could be gone or stolen second day.
