It's 3G, not G3. 3G means 3rd Generation. CHA and CHL have 3G but don't do WCDMA as well as CHU. See this:

"On 7 January 2009, Unicom Group was granted the license to operate 3G digital cell business with WCDMA technology by the Ministry of Industry and Information Technology of the People's Republic of China ("MIIT"). MIIT has also granted approval for Unicom Group to license China United Network Communications Corporation Limited, a wholly-owned subsidiary of the Company, to operate 3G digital cell business with WCDMA technology nationwide in China."

The WCDMA is the kick-butt part of what they offer. This could be a $40 stock if they can get market share from CHA/CHL.
