I got the same on my order, either thats when our pre-order will be fulfilled or more likely just what they always put. I have read before that 3-4 weeks was stated on the email.
I think despite all the rumours on when these will appear we can be fairly certain it will arrive in the next 3 weeks, Possibly as early as the end of this week. We have been told for a long time by Nokia that in some markets it will start to ship in October. I know also from historic reports on phone releases that Nokia Shop UK definitely does get the phones on their first release and usually fulfils all the orders on the day of release. I haven't heard of people historically talking about being in particular batches of phones for Nokia shop while you do get such conversations on the release of a product from expansys, I suspect that Nokia can tailor the production to meet the known orders at their store. Anyway thats my hope!
I went for free delivery so I will know when it gets in the post several days before it arrives unlike those unlucky souls who get little time to prepare for the arrival of their new device!
I am betting that it will appear at my door second week of November.
