The mobile unit of AT&T Incorporated, which is being rebranded from Cingular Wireless, has received about 1 million requests for information on Apple Incorporated"s new iPhone, AT&T Chief Operating Officer Randall Stephenson said during a keynote speech at the CTIA wireless technology conference: "One million people have asked us to call when this phone is available." While the biggest U.S. wireless service is not taking advance orders for the phone, it set up a section on its Web site inviting visitors to leave their e-mail addresses to receive information about the phone when it is released. AT&T will be the first U.S. wireless service to sell the music-playing iPhone when Apple begins selling the phones in June. The iPhone sports a 2 megapixel camera and will be available in two models, 4GB and 8GB priced at $499 and $599, respectively.
