China Unicom has announced that it has signed up only 5,000 new iPhone subscribers in the first five days the device has been on sale, but adding it was satisfied with the results. Unicom Chairman Chang Xiaobing said that the company is “satisfied with iPhone sales so far,” and added that the launch would help boost revenue in the fourth quarter, without providing any additional details. Reuters reports that analysts expect Unicom may be forced to offer more subsidies on the iPhone to bring down its price and boost sales. China Unicom became the first carrier to offer the iPhone in mainland China when it launched the device October 30.
