You and I are on the same boat. Still processing for me too
although mine was the 256g version unlocked GSM.
I spoke to Apple why some orders are getting into PFS early, even when they have ordered late.
There are possibilities which depending on Colour, Storage GBs etc.
It could also be that someone cancelled and that person's order got shifted early.
Apple also said, there are cancellations going on since people are picking it up from the stores.
It could also be a possibility that online it won't show any stock but the stores might have. They get sold really quick.
I've been told that just before 10/25 like 2-3 days before it should go into PFS. This is just an estimated time delivery, it could be much more sooner also but they don't want to give the false guarantee.
Also, I've been told, Jet Black is in huge demand and may take some time.
Hope this helps everyone.
