Gresso, a design house which specializes in creating customized expensive and exotic renditions of devices, has just released a $30,000 diamond bedazzled iPhone 4. The Lady Blanche features a coating of diamond-coated mineral glass on the case and six panels imbedded into the back of the iPhone. Three contain Swiss watch movements, each showing the time in a different time zone. The other three chambers contain diamond crystals freely floating around.
