Stan Sigman of AT&T called the iPhone the best device he had ever seen when it was unveiled in 2006. AT&T has an exclusive deal with Apple to carry the iPhone, but the terms of the deal that was made in 2006 are kept confidential and it is unknown when AT&T will lose its exclusivity. This lack of information in the marketplace hurts consumers who want an iPhone but not on AT&T as they are locked into two-year agreements until the exclusivity ends.
