"iPhone 4 pre-order sales yesterday were 10-times higher than the first day of pre-ordering for the iPhone 3G S last year. Consumers are clearly excited about iPhone 4, AT&T's more affordable data plans and our early upgrade pricing.
Given this unprecedented demand and our current expectations for our iPhone 4 inventory levels when the device is available June 24, we're suspending pre-ordering today in order to fulfill the orders we've already received.
The availability of additional inventory will determine if we can resume taking pre-orders.
In addition to unprecedented pre-order sales, yesterday there were more than 13 million visits to AT&T's website where customers can check to see if they are eligible to upgrade to a new phone; that number is about 3-times higher than the previous record for eligibility upgrade checks in one day.
We are working hard to bring iPhone 4 to as many of our customers as soon as possible."
