Well, according to comments on this thread:

- Nokia.co.uk have never heard of Nokiaretail.co.uk.

- Nokiaretail.co.uk (owned by MPD) claim they they and Nokia are basically all the same.

But anyone can claim something without it being true.

Draw your own conclusion...

For now, I'll trust Nokia.co.uk and they have said they are shipping to pre-order customers today and on Monday, (and that they are not the same as Nokiaretail.co.uk and MPD).

We'll know early next week if that's true.
