Paul Thurrott is an insider when it comes to Windows Phone 7. He’s not an employee of MS but was granted early access to WP7 information and is writing a book about WP7. So when he says he has a reliable source, that has a lot of credence to it. And here’s what he has to say:
I mentioned on this week’s Windows Weekly podcast that the October 11 date people have been tossing around for the Windows Phone launch was incorrect. (Microsoft is holding an annual event in NYC on that day, but it’s unrelated to Windows Phone.) While I don’t know anything about a European launch, I’ve been told by a very reliable source that the US launch date for Windows Phone is November 8.
