Carrier sometimes resistant to unlocking devices
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.
Most of the messages to Cook complained about not being able to use their iPhone on carriers outside the US, and said that AT&T had previously refused their requests for an unlock. Carriers like AT&T are sometimes unusually strict about unlocking iPhones, even when a subscriber is finished with their contract. Some people may be allowed, while others will be redirected to Apple, or just outright rejected.
