China Unicom increased both its subscriber base and profit for 2011 by spending heavily to promote 3G data use, which is still relatively new to the country, Marketwatch reports. The company more than doubled its 3G subscriber base to 40 million users, now 20 percent of its total mobile base, and increased profits in the 3G arena to 31.7 percent of its revenues. The company credited its collaboration with Apple for part of the results.
