I think people have misunderstood my intentions here.
Initially I was offering the ability to purchase (from Apple) the iPhone I had reserved at the store as I already had one paid for and in transit.
Sorry to have caused any confusion, especially to the extremely deluded person who PM'd me and said they take it off my hands if it was under £500. I think I'd be selling them all day if I was selling £600 handsets for under £500!!
I've now collected the handset from the store and have been using it
I've not decided what to do with the second one yet. I was going to send it straight back but Carl suggested eBay as did the guy in the Apple Store however I think her indoors has taken a shine to it as well.
