Greetings from Switzerland !
64 GB Space Grey here.
I was ready at 8:50 GMT+1 with iPad on wifi and iPhone on cellular and the store app... plus my iMac on Safari. But then it all kinda f*** up.
Apple Store opened up only 10 minutes after 9 for me, then it wouldn't recognise my Apple ID password (something about a connection to a ??? server, not a "wrong password" notification). I had to go an change my password, which obviously took a few minutes... by then the delivery dates had slipped to 4 weeks, so end of November it is for me.
I'm putting my 6s plus 128 gb on a diet, so that it slims down to fit into 64 GB.
