I spoke to the manager of the london flag ship store at lunch time today. He told me it was general sale 4th dec and monday for all the preorders (which were a priority)

Although I have my doubts about their accuracy, especially as last night I was told friday at the latest (friday 28th) and today they told me no one had received their N900s yet as they weren't available (obviously not seen this thread, then!)

I'll hold out until monday to be deeply disappointed again..
