If you collected more money for iPhone 4 than the cost of the phone, you can always spend them on more expensive version of the same device. This is a luxury version of the iPhone 4 with diamonds inlaid with shell. This means that it is not very clear whether you can order it before the supply of white iPhone to officially begun, but at a price of $ 20,000 sure would not hurry too. If by chance you’re wondering whether you will still have to sign a contract with an operator, even if you pay a similar amount for the phone, the answer is no, the phone is sold unlocked. If you currently think about the problems of the iPhone 4 range, do not rush to conclusions – after all, diamonds are a great insulator.
