Following the official launch of the iPhone in China the main carrier China Unicom confirmed that it had signed up more than a million subscribers but only 5,000 iPhone customers.

Reuters reports that Unicom Chairman Chang Xiaobing said his company expects to add a million new 3G subscribers each month and that it was satisfied with iPhone sales so far.

The iPhone was released in China last Friday, the top end iPhone 3GS is available without a contract for 6,999 yuan, or $1,024. No iPhone handsets currently have any Wi-Fi capabilities but new models are expected to be released before the years end with Wi-Fi built in. The discrepancy reportedly comes from the Chinese governments ban on Wi-Fi which was lifted in May, after the current models were manufactured.
