You work for UPS? How would you know all that? And if so how certain are you about it being on that plane?
At this point no one is showing a departure scan on UPS99 so their system is obviously back logged but, again, given the size of the aircraft I would be very, very surprised if all the phones couldn't be accommodated. It is possible, but haven't seen a delay in Incheon for any phone previously. 1-3 day delays sitting in ZhengZhou are the norm.
