The HTC Windows Phone 8X and the Nokia Lumia 920 are part of the first wave of Windows Phone 8 devices. While the devices will probably be unveiled officially on October 29th at the scheduled Windows Phone 8 event, both devices will be available on pre-order through AT&T starting October 21.
The smartphones are expected to be available through retail stores sometime in early November, which indicates that the pre-orders should have started shipping by then.
Additionally the Samsung ATIV Smart PC and the Asus Vivo Tab RT are also reported to be available on pre-order starting October 21, with their launch expected to be on October 26th, the same day Windows 8 is set to launch.
