So, this was the interesting conversation I had with Live Chat a little while ago. Names changed to protect the innocent;
O2: Hello. I hope you're well. What can I do for you?
ME: Hi, what's the latest with my iPhone order? I've had no text or email and no update.
O2: Thanks for sharing. I will check your account and assist you with that, needn't worry.
O2: Thanks for your patience.
I have checked your account and the order has been processed. Even a new handset has been assigned to you; however, your handset is waiting to be dispatched from our end.
You will receive an e-mail confirmation as soon as the handset gets dispatched from our end and you can expect the delivery within a week from today.
ME: But you don't have them in stock at the moment do you?
O2: Yep, we do.
ME: So why will it take a week for dispatch? I'm confused by that
O2: It won't take a week, you will receive the package within a week as that's the max time frame.
O2: It will be dispatched either by today or by Monday.
ME: Oh ok, as I'd been led to believe I'd have to wait at least four weeks
O2: You won't have to as the phone has already been assigned to your order.
ME: That's excellent. Sorry to ask, but how certain are you?
O2: You're welcome. This is because I can see the handset_stock_id updated on your order.
I so want to believe this, but as I have ordered a 7 Plus 128GB in Jet Black, I'm not sure that I can....
