AT&T has started selling the iPhone 4 both online and at its retail stores, leading to another round of lengthy lines for the popular new handset. Mac Rumors reports that some lines are more than one hundred customers long, and a search of Twitter shows a large number of people in lines across the country.
AT&T was originally expected to offer the iPhone 4 on launch day, announcing only two days prior that it was pushing its walk-in sales launch back to June 29 due to limited supply. AT&T is offering the iPhone 4 on a first-come, first-serve basis.
