Canadian carrier Rogers and its sub-brand Fido have brought back a system that would let customers more officially unlock iPhones after the sale, a possible leak of its strategy has uncovered. As part of a broader move that would let any subscriber out when out of contract, Rogers has let users get an unlock by calling its help line and having them contact Apple. Once greenlit, the phone needs only to be restored in iTunes to remove the restrictions, iPhone in Canada was told by Fido user Argun Tekant.
