BGR is reporting that AT&T has sold out the entire allocation of iPhone 4s that will be available on iPhone 4 Launch day. Check out the official statement from AT&T below:
"Because of the incredible interest in iPhone 4, today was the busiest online sales day in AT&T history. As of Tuesday afternoon, customers who preorder iPhone 4 moving forward will receive their device on June 25 or later, depending on when the order is placed. We'll email customers with confirmation once their order is placed, and again when it ships. In addition, we will have devices available on a first-come, first-serve basis in our stores beginning on June 24."
There has been no word from Apple on the condition of their stock, but I have a feeling it might be getting low as well with all the problems the servers have had all day.
