Vice President of China Unicom, Li Gang, told reporters that his company has completely sold through their first shipment of iPhone 4s. The shipment, which totaled 100,000 units, took just four days to sell out. The Chinese mobile operator also reported that over 200,000 customers have pre-ordered the device; the company has since stopped taking online reservations due to the demand. When the iPhone 3G and 3GS launched, it took one month for China Unicom to sell 100,000 devices. Analyst Liu Liang credited a record number of Chinese mobile users adopting smartphones, as well as positive media attention around the iPhone 4, as possible reasons for the strong sales numbers. China Unicom is expected to get their next shipment of iPhone 4s around October 1.
