You are not mistaken, this diamond version of iPhone 5, which costs as much as150,000 dollars, is the most expensive mobile phone at present. It is reported that this mobile phone was built by Stuart Hughes, a British luxury goods merchant. It uses a 24K pure gold shell, and more than 600 white diamonds are inlaid on both sides and back of the fuselage. Even its Home button is inlaid with a precious 26-carat black diamond. To be sure, the diamond version of Siri of this phone will be much more pleasing to the eye than Siri of other ordinary iPhones.
