Well I don't have a clue what's going on. I ordered the phone from O2 on the 28th and got a text message stating that it would be delivered next day (which it was):
"Your O2 order is estimated for delivery Tuesday (29th). Te reschedule...visit UKmail.com"
This suggests it would be delivered by UK Mail, though I can't remember who did actually deliver it.
Later on the 28th, the day I ordered, I got two identical text messages within a few minutes of each other:
"Thanks for your order, your accessory item has been shipped by Royal Mail this will be with you within the next 1-2 days" - I assumed this would be the accessory pack.
Nothing has arrived, then today, 3 days later on the 31st, I got this text message (at 5:41 a.m.!)
"O2: Oops we forgot to send you your redemption leaflet with your Nokia 930. Sorry about that. The leaflet should be with you by the end of the week."
Anyway not wanting to take any chances and with stock running out fast it seems (not surprising if a lot of people are getting two or more) I went to the link online to try that, and managed to place an order for the yellow one which was the only colour they had left in stock. The confirmation email suggests that everything is in the pack:
L93PKYL: Lumia 930 Wireless Pack incl MD-12, DC-50, App Voucher
I have no idea what O2 are supposed to be sending out!
