Best Buy is set to become the first major U.S. retailer to sell the iPhone in what some are seeing as a major victory over rival Circuit City. With the iPhone, Best Buy is looking for the device to help drive customers to their stores for the upcoming holiday season. For Apple increased distribution of the iPhone could help it reach its sales goal of 10 million iPhones by the end of the year. The iPhone will still require a two-year service contract with AT&T when purchased at Best Buy. Currently, AT&T is saying there is a 7-10 day wait for iPhones at its retail outlets and hopes to eventually reach the goal of being able to provide same-day sales. When Best Buy begins selling iPhones on September 7 this could put added pressure on product availability although Apple recently promised to increase production levels.
