I ordered from EE and from Apple direct, I ordered with EE after I'd ordered from Apple, but decided to just get the one from Apple directly as it'll be unlocked and I can use my sim only deal on it from EE which was a fabulous deal!
According to the apple website mine is preparing for dispatch. I ordered via the Apple Store App on my iPhone as it went live at bang on 8.01 and got the confirmation at 8.03.
It seems to have worked again as this is what I did with my 6S Plus, the page didn't go live on the website until about 8.10 again and already the Jet Blacks were out of stock, luckily I wanted gold to match all my other stuff though. I go in the day before, add the phone and the spec to my favourites, make sure my preferred payment method is updated and then just add it to the bag and click checkout, enter the 4 digits on my Amex and the sale was done there and then, got the confirmation straight after, it's been showing as preparing for dispatch since Saturday.
