Sina released yesterday the first "3G Investigation Report of Internet Users All Over the Country" through a survey of 363,000 Internet users. The report pointed out that after large-scale promotion by service providers, awareness of 3G has increased significantly among Internet users and close to 60% of the users said that they would definitely upgrade to 3G. However, the high cost is still the biggest barrier for users to upgrade at present, while the demand for 3G mobile phones remains focused on mid- and low-end markets.
