The most expensive iPhone in the world

The casing of the exclusive iPhone 3GS Supreme was created using 271 grams of 22 carat solid gold.
The front bezel houses 136 flawless diamonds totalling a massive 68 carats while the Apple logo on the back is made from a further 53 gems.
The front navigation button is made from a single diamond of more than seven carats.
Designer Stuart Hughes, from Liverpool, Merseyside, took ten months to make the phone after it was commissioned by an anonymous Australian businessman.
Mr Hughes said: “The Iphone is the phone with the most tricks on the market.
“What possibly could we do to trick it up more? Bless it with the finest precious metal and jewels.
“Most of the ten months was spent trying to source the diamond for the navigation button.”
The phone comes in a special 7kg chest made from a single block of granite and Kashmir gold with a Nubuck leather lining.
