I ordered CPW too. 64GB SG SIM free, 1st acknowledgement email 07.55 and second 10.08. Also phoned yesterday to be told 3rd November is accurate. However, I'm not cancelling my 2-3 week Apple order until I have definitive knowledge of CPW order (i.e. delayed date or phone in hand).
Yeah, I am the same but with Vodafone. I simply don't trust a telephone sales rep promising me that I will get the phone next Friday.
There is no email acknowledgement from the carrier, just a web order number when I completed the upgrade process. I am told I will receive an email next week confirming.
I'll believe it when it arrives and then I'll cancel my 2-3 week Apple order.
