Okay you guys I need answers

SO I pre-ordered my HW back in March
I had it going 2 day delievery to a APO, AP address
SE accepted payment and shipment information 166.00

Cool

I got shipping information yesterday woohoo excited that my order was being processed

Today I got word that UPS was unable to deliver APO,AP
and that it was being returned to sender , and will find alternate means to deliver product....WTF

Early Access ends on Saturday

So

I can imagine it taking maybe weeks now to get

Can I go to the store and pick up any HW and play it on my CE account . If I buy ps4 can I play on ps4 ? And wait for my CE to get here ?

And once my CE gets here if I haven't typed in that registration code can I give it to my a friend from the CE I bought but didn't type in the code for ?
