In a press release, Apple says that it has sold out of its available inventory for preorders of its new, taller iPhone, and that "while the majority of preorders will be delivered to customers on September 21, many are scheduled to be delivered in October" instead.
AT&T, one of the three nationwide US carriers for the iPhone, also reported that the iPhone 5 was the company's fastest-selling iPhone ever.
The carrier said customers ordered more iPhones from AT&T on the first day of preorders and over the weekend than had ordered any previous versions of the phone.
The same comments were reported from telcos all over the world as the iPhone 5 effect kicked in.
The iPhone 5 is due to arrive in stores - and the homes of at least some preorderers - on September 21.
