Although Windows Phone 8 handsets aren't expected to launch until October 29, rumor has it that several will be ready for pre-order from AT&T as early as October 21, according to The Verge.
Inside sources have revealed to The Verge that the carrier will begin taking pre-orders on the HTC 8X, Nokia's Lumia 920, Samsung's Ativ Smart PC, and the Asus Vivo Tab RT.
AT&T is slated to sell both Nokia's Lumia 920 and 820 Windows Phone devices, which are the latest in the carrier's lineup of mobile devices. The Lumia 820 will be available from other carriers, such as T-Mobile, but the Lumia 920 will be exclusive to AT&T.
The pre-orders are said begin on October 21 and the official launch will be on October 29, but the smartphones won't actually be available until early November, according to The Verge.
CNET contacted AT&T and Microsoft for comment. We'll update the story when we get more information.
