Worldwide sales of 4G LTE smartphones from LG have surpassed three million units, the company announced over the weekend. The South Korean manufacturer released its first 4G LTE smartphone in the United States on Verizon Wireless last year, the Revolution, and has since expanded its market to Europe and Asia. LG is currently selling LTE smartphones in 10 countries and plans double its reach by the end of 2012. The company’s Optimus LTE handset recently surpassed one million units sold in Korea, becoming LG’s first smartphone to achieve the feat.
