"Apparently, this 64GB iPhone 4 is not for sale in grey markets of Hong Kong. The owner of this engineered prototype told us that he got it from a source who has a small quantity of these prototypes. They are definitely leaked from Foxconn's factory in Shenzhen. What's more, according to the owner, he believes that the next iPhone will bring 64GB storage capacity to users. Well, we think Apple is planning to update the iPhone 4 with small upgrades, at least featuring a new 64GB model."
