I think the ones who are stuck in Shanghai, China who was originally scheduled for Monday or Tuesday will get their phones no later than Tuesday. However the ones stuck at ZhengZhou, China who was scheduled for Thursday 25th will get theirs on their scheduled date but could be moved earlier only by one day moving it to Wednesday 24th.
However we can confirm this in about 8 hours or less tomorrow morning as UPS will update all their tracking tomorrow morning. UPS is sometime lazy about updating over the weekend for some strange reason. The planes could actually be in USA right now but the tracking is not reflecting that at this point of time. Again tomorrow morning will tell all.
