AT&T also reiterated its [url="https://www.macrumors.com/2010/05/19/atandt-executive-downplays-effect-of-eventual-loss-of-iphone-exclusivity-on-business/"]position that AT&T customers will not defect to rival carriers in large numbers once the iPhone goes non-exclusive, claiming that 80% of customers are on family or business plans that make it difficult for them to switch.
Good old AT&T. We'll keep our existing customers, not by giving them good cell service, or good customer service, or competitive prices, but by making it incredibly expensive and difficult for them to switch to the competition.
