Well, I asked nokia.uk over e-mail about my order a little over a week ago, and on the 12th they said 'tentative date' the 19th. I should probably have assumed that if the date is still tentative with 1 week to go, then clearly they aren't going to make it.

This morning I received an e-mail from Nokia, first thing...I opened it with excitement to find...it was a request to feed back on their service having contacted them previously. ;-(
No other word from them yet. I've e-mail again to see if we can do better than 'tentative'
It does seem strange that they can't be more fixed in their predictions. And it really is poor that they haven't kept pre-order customers in the loop without us having to chase for details. What could possibly be going on with their logistics if they are unable to specify a date with confidence, when we are supposedly so close to it?
