So we all knew when Microsoft Windows Phone 7 smartphones where going to surface and now it appears we know when we are likely to see some Windows Phone 7 devices coming to the Big Blue network

According to an article over on Engadget by Vlad Savov, the people over at the Wall Street Journal have said that AT&T and Microsoft are planning a WP7 debut event for the 11th of October in the United States, but just when will said WP7 devices launch?

Well apparently they will launch on AT&T during the week of November the 8th. AT&T is said to be the exclusive carrier for Windows Phone 7 devices which will be from the likes of HTC, LG, and Samsung although which smartphones have not yet been confirmed.

Apparently as AT&T became the early exclusive carrier in the US for WP7, Microsoft is to receive AT&T marketing support to help push out the message of the WP7 release.
