Please remember that nokia.co.uk and all the other Nokia web outlets are not necessarily anything to do with Nokia at all (the UK one is outsourced, I assume the rest probably are too)

Nokia have only said that the products shipped last week, nothing else.
The web shops may have guessed at other dates, but this is not Nokia.

Agreed it's frustrating, but Nokia haven't lied about anything.
Not giving the information we want isn't the same as lying.
