Finally I realize that the white iPhone 4 is actually black iPhone 4 in white coat
. It seems that I had to wait another few months for my white iPhone 4, because I don't want on black iPhone with white coat. If I want, I would rather change different clothes for my black iPhone 4, because I found a very great website store where a lot of phone cases are on sale. So I can change different kind of clothes in different colors for my black iPhone 4 every day. If you want to change clothes for your iPhone, you can have a look. The website is named Dinodirect http://www.dinodirect.com/iphone-cases-f-cell-phone-pda-accessories/ .
