it can be harder for apple to do it. instead it might be easier for apple to help both china telecom and china unicom to move to FDD LTE faster. it would take another couple of years for china mobile to move to TD LTE because they are not eager to upgrade. china mobile is the big fellow already. apple should not work with them if terms are not pleasant. if unicom and telecom can provide better and faster LTE services than china mobile, iPhone will thrive.
