AT&T is allegedly reversing its position on limiting iPhone sales to one per customer, and returning to the company's former three-per-customer rule after finding sufficient stock of the device to do so. InformationWeek writes that the announcement only comes after one day of restricted sales, but AT&T is supposedly restricting sales of the iPhone to credit and debit card purchases. AT&T would not comment on inventory levels of the device.

"Our No. 1 concern is to make sure that every customer who wants an iPhone gets one," an AT&T spokesman said. "We thought yesterday that the fairest way to do that was to limit customers to one iPhone. Then we realized that we have sufficient inventory to go back to our original policy."

Apple is currently in the midst of releasing iPhone 2.0 – a title incorporating a new 3G version of the device, with a brand new software developer's kit designed to allow third party applications.
