Quick, we've located a white iPhone that's in stock and ready to go. That's the good news about the iPhone 4 Diamond Edition.If you love your bling, there's another big selling point too - the Diamond Edition is full of it. The whole of the surrounding frame is encrusted with 6.5cts of top quality VVS, colour 'F' diamonds. If you know your precious stones, you may or may not be impressed by that.But there's more. Not just any Apple logo - the rear of this iPhone 4 houses a solid platinum and diamond Apple logo. Maker Stuart Hughes describes it as a work of art, we think it's a bit flash. The truth is probably something of both.Of course, it's an iPhone 4 too, an ultra-rare (right now) white one at that, with 32GB of storage and unlocked to use on the network of your choice. It even comes with a special case, a 'luxurious hand finished wallet made from real Ostrich foot' that also holds four credit cards. Because if you're buying one of these, you are the kind of person that uses and carries four credit cards.How else will you be able to afford the £12,995 asking price? Yes, you read that right, just under £13k for a mobile phone. But at least you'll be secure in the knowledge that it's a limited edition of just 50.
