China Unicom plans to charge 2,500 yuan, or roughly $366, for the 8GB iPhone 3G when it launches the device in China, according to a new report. Chinese-language cnBeta reports (Translated Link) that the company will be offering that price with a two-year contract agreement, at a minimum monthly rate of 186 yuan, or roughly $27. Based on numbers reported in an earlier article, this would place the iPhone 3G below the cost of most high-end phones on the Chinese market, but above the cost of non-smartphones; the monthly charge would be roughly four to five times current average monthly service fees. The report also suggests that pricing could possibly be adjusted before the official announcement, and does not offer any specifics on whether 16GB or 32GB models will be offered. According to a Reuters report, an official announcement regarding the Apple and China Unicom deal could come as soon as tomorrow.
