AT&T and Apple recently announced that the innovative iPhone 3G will be available in the U.S. on July 11. iPhone 3G combines all the revolutionary features of iPhone with 3G networking that is twice as fast as the first-generation iPhone, built-in GPS for expanded location based mobile services, and iPhone 2.0 software which includes support for Microsoft Exchange ActiveSync and runs the hundreds of third party applications already built with the recently released iPhone SDK.

“We’re offering the most advanced mobile device ever on the nation’s most advanced high speed network,” said Ralph de la Vega, president and CEO, AT&T Mobility. “We think iPhone 3G is an amazing mobile device and our customers are going to love using iPhone 3G to make calls, send emails and surf the web even faster.”

“We’re thrilled to continue working with the largest wireless carrier in the US to bring iPhone 3G to AT&T customers this July,” said Tim Cook, Apple’s COO. “iPhone 3G is a revolutionary product and we can’t wait for customers to get their hands on it.”

AT&T’s wide 3G mobile broadband network offers 3G mobile phones download speeds of up to 1.4 Mbps. AT&T’s 3G network is currently available in more than 275 leading U.S. metropolitan areas and by year-end, the company plans to offer 3G service in nearly 350 metropolitan areas.

iPhone 3G will retail at USD $199 for the 8GB model and USD $299 for the 16GB model in both Apple and AT&T’s retail stores, and requires a new two-year contract. AT&T will also sell iPhone 3G through its direct business sales teams.
