Chinese mobile services provider China Unicom has reportedly sold 100,000 iPhone 4 units within the first four days of its launch in the country.
Company executives said that China Unicom, which is the official iPhone 4 provider in the country, is almost out of iPhone 4's owing to the huge pre-order demand and in store sales.
Earlier, the company has reported that it had received a whopping 200,000 online pre-orders for the iPhone 4, forcing it to stop taking them and advise users to visit the retail stores.
Considering last year's iPhone 3G and 3GS launch in the country, the iPhone 4 has proven to be far more popular and in-demand than its counterparts. Last year, China Unicom had sold only 5,000 units within the first week of the launch.
According to AppleInsider, China Unicom's lucrative iPhone 4 contracts might be a driving factor the massive popularity the smartphone is enjoying in the country.
If customers get into a 2 year 286 Yuan per month contract for the 16GB iPhone 4, they won't have to pay anything for the phone.
