When the iPhone was announced in the summer of 2007, the phone was not the only shocking part of the announcement. The fact that Apple had carrier exclusivity with AT&T shocked the industry. While many phones have been pushed onto as many carriers as possible, Apple took a different approach and reached an exclusive deal with AT&T that lasted until February of 2011.

Despite new competition for the iPhone with Verizon and Sprint, many iPhone owners that were already on AT&T have remained loyal and stayed with the carrier.

Glen Lurie, AT*T’s president of emerging devices, recently said that not many have people have jumped from AT&T to other carriers.

“Churn has not moved at all,” said Glen Lurie, president of emerging devices for AT&T. Churn refers to the number of customers who cancel services.

Lurie said the carrier’s relationship with Apple Inc., maker of the iPhone, has been positive, and they’ve had record-breaking sales of the latest iPhone 4S which has led to some supply issues. U.S. consumers are looking at a week to two week wait times to get the latest iPhone 4S from AT&T, he said.

With the very successful launch of the iPhone 4S, with the sales of over 1 million units sold, there was only a slight decrease in the amount of activations for AT&T. AT&T has also been noted to have been the fastest of the three carriers in terms of data speed.
