Several more people have come forward to say that Apple CEO Tim Cook's office is helping people getting AT&T iPhones unlocked, according to 9to5Mac. A single incident was reported in late March, but 9to5 now says that a "significant number" of its readers have received help from Cook's staff. In particular, it says that "upwards" of six readers have been given exceptions by AT&T Partnership Operations after emailing Cook. The emails from AT&T tell users to tether their iPhones to iTunes to complete the unlocking process.
