By any chance did you enquire about 16Gb model availability at all?
If they confirm they'll have them, I'm going to Apple.

Oh, no I forgot, sorry. Actually that's a good point. It's probably safer to go to a small Carphone Warehouse - they should getting fractioned units (2/3 8GB, 1/3 16GB), and they won't sell too fast.
And by the way, I don't know what these CPW haters are on, but I have had nothing but great experiences from them. Infact, I have had much worse experiences from O2 stores.
You enter the store, and they run into you dictating deals and tarrifs and never leave you alone to browse. In CPW, you can feel free to do what you want and the insurance they offer is much better.
Infact, the best is cancellation insurance, you can cancel your contract around 9 months in, which is just after MacWorld '09, so you can get the iPhone v4

.
Also, I think you can return your iPhone, used, with box and in good condition before the 14th day of the contract - don't hold me to that though, that's just what I've heard.
About the Apple Store:
Call 020 7153 9000 and press 4. They're still open, and there wasn't a calling queue when I phoned.
Good luck and report back!
