My fren ordered 1 unit from apple online store, then the unit came 1 day later. Bought powersupport air jacket. Then installed, i felt that the casing is loose. Then i tot is the casing lousy.. i open out then i put on flat surface.. the phone is rocking lolz.. now he is trying to get it replaced but they ask him to call apple damansara but they like very busy or no ppl picking up the phone. i asked him to ask apple online chat to open a case ID, so it has to be closed and get tracking.
