Just two days after the release of the 3G iPhone, grey market merchants in Shanghai have begun to accept pre-orders.

Although the iPhone 3G was launched for only two days, it has already stirred up the gray market in mainland. After visiting several digital shopping malls yesterday, the reporter found that many sellers who sold gray-market i-Phone mobile phones have made advertisements such as "iPhone 3G mobile phone (8G), pre-estimated price at 4000 yuan". The futures price of the memory of 16G was priced at as high as 4680 yuan. Industry insiders reminded that the system of Apple's iPhone 3G mobile phone was WCDMA while the currently trial commercial-use 3G network system of Shanghai Mobile was TD-SCDMA. Therefore, even if one got an iPhone 3G mobile phone, he or she could not use the 3G service in mainland.
