Although Apple still did not released iPhone 7, you have now ability to pre-order it but not any version. Actually there is one company called Legend which makes special edition or to be precise it will offer iPhone 7 with diamonds and gold called Qatar edition with price approximately $4,000.
But it is also interesting that the Legend states states that the new iPhone will have 256GB of storage space. Also if this is not enough for you then you can choose ruby version of iPhone 7 which costs only $6000!
