It would appear most of those pre-ordering so far have pre-ordered with Apple directly, so I thought I'd share my experiences of upgrading with Three.

Honestly, this was the most excruciating upgrade experience. I've got until next September before my contract ends, so had to upgrade via telephone to pay the early upgrade fee. Three released pre-orders at around ~7:50am on their website and a couple of people had Tweeted them to say they'd placed their orders.
I rang a little before 8am and despite calling from my Three mobile, it insisted on me entering my mobile number etc. into the IVR. I selected the option for 'thinking of leaving' rather than 'upgrades' and was told the department was closed and would open at 8am - it was 8:02am.
I called back and finally got entered into a queue - in the meantime, I used another phone and called through and selected the 'upgrade' option - both in a queue. I was answered at around 8:31am on the initial call and in typical fashion got connected through to the agent most pleased with the sound of his own voice.
I explained exactly what I wanted, and no changes to be made to my plan. However, he had me repeat the colour and storage option several times by asking the same question in several ways, and then repeated/mumbled what I was ordering etc. And then the usual whether I was happy with the service, the price plan, the data etc. I know when you're eager to get something, a minute can feel like an age, but I've received the confirmation SMS from Three at 8:43am. In other words, it took 12 minutes to process this upgrade - no haggling, no special promotions/discounts.
I was told by the operator the handset would be delivered on November 10th. When I stated the website was promoting November 3rd and if I could not receive the handset on November 3rd I would cancel, he told me I could look to receive the handset on/before November 10th. I'm not too bothered at this stage, we know the handset stocks are limited. Three use DPD so I shall know on November 2nd through the DPD app. whether I have a package coming.
At the end of the call, the operator told me I would have to listen to a short recording of the T&Cs and it would not process my order until I selected the appropriate option at the end of the message. Sigh. I listened to the recording and there actually wasn't an option and the call is terminated at the end of the recording.
