I've been following this thread for a while, thought I'd sign up and tell my tale
I've been to 4 different apple stores as well as buying online (apple) and I've had no luck getting one, Regent Street, Westfield, MK and Watford
I gave up looking for one as apple online delivery date had changed to middle of October.
After reading many reviews I ordered the HTC One X and expecting delivery of it on Saturday, was heartbroken at this point really wanted the 5
Then I called the Carphone Warehouse on the off chance they have one in stock, and YES!!!
Managed to get a sim free 32GB in White, they had 64GB as well but thought I won't use all that!
I paid £7.50 extra to have it delivered to me tomorrow by Yodal, the guy I spoke reassured me they had it in stock over and over!!
So those of you wanting sim free's try Carphone Warehouse, I have read they aren't essentially sim free as they lock them selves when you insert a sim, tbh I'm not to fussed when I go abroad etc I tend to use roaming and I never leave Europe tbh!
Called orange and they are sending me a nano sim they said it'll take up to 4 working days, but you know I've waited this long what's another week!
