Customers may be able to get their hands on the latest phones from Microsoft a bit early.

Unnamed sources are claiming that AT&T will begin pre-orders for the Microsoft HTC smartphones starting October 21, according to  The Verge.

Pre-orders are rumored to be available early for the HTC 8X, Nokia's Lumia 920, Samsung's Ativ Smart PC, and the Asus Vivo Tab RT.

On September 19, HTC unveiled the two new Windows Phone devices, the 8X and 8S, which run on the brand new mobile operating system from Microsoft. The announcement took place at an event in Manhattan by Microsoft CEO Steve Ballmer who was joined by HTC CEO Peter Chou.

The HTC 8X will be the most powerful Windows Phone from HTC while the HTC 8S will fall in around the mid-range. Some of the features that both phones will share will be the colorful new design made from polycarbonate which is both very light and scratch resistant. Both phones will go beyond the normal black and white looks and will be available in an array of vibrant colors. They'll also include Beats Audio to provide improved music playback and the displays will use Corning's Gorilla Glass protection.

The 8X comes with a 4.3-inch 720p HD display, 1.5-GHz dual-core Snapdragon S4 processor, and an 8-megapixel camera. The 8X's user-facing camera rates 2 megapixels and includes a wide-angle lens for better video chats. It also includes a dedicated 4-volt amplifier that will boost the audio signal sent to headphones.

The Windows Phone 8X by HTC will be sold by AT&T, T-Mobile USA, and Verizon Wireless. It will support LTE and HSPA+ wireless networks.

The 8S will have a 1-GHz dual-core Snapdragon S4 processor, a 4-inch display, and a 5-megapixel camera. It won't feature the user-facing camera and the LTE 4G versions of the phone are not expected. It's yet to be seen which U.S. network operators will sell the 8S.

The Windows Phone 8 will release on October 29 and be available in early November. Prices have yet to be announced.
