The HTC HD2 -- the uber-smartphone previously known as the HTC Leo -- will be released in the U.S. in the first quarter of 2010.

This model will be released in Europe later this month, but at launch won't offer support for the version of 3G used in N. America. However, Peter Chou, HTC's CEO, told SlashGear that his company is working on a version of the HD2 for the U.S.

This will give American's access to this smartphone's high-end features, like a 4.3-inch WVGA display and 1 GHz processor.

Chou said this device should debut during the first three months of next year, but he didn't say if it will be offered by any wireless carriers. If necessary, HTC has the option of selling the HD2 directly to consumers.

The head of HTC didn't say what it might cost.

An Overview of the HTC HD2
The HD2 will be one of the first devices on the market with Microsoft's Windows Mobile 6.5 Pro, but have the new version of HTC's custom user interface layered on top. This used to be called TouchFLO, but has just been renamed HTC Sense to reflect a greater focus on consumers.

It will lack a hardware keyboard, but that's just about the only feature it won't have.

It is going to be the first Windows Mobile smartphone with a capacitive display that supports multi-touch, so users can resize websites, Microsoft Office files, PDF documents and pictures easier with a pinch of their fingers.

This display will be the largest yet on a smartphone running Microsoft's OS, and will have a WVGA (800x480) resolution.

Naturally, the HD2 will have mobile broadband (7.2 Mbps HSDPA), plus it is going to include Wi-Fi b/g and Bluetooth 2.1. It will even be able to act as a Wi-Fi router for another computer.

It will also include a whopping 448 MB of RAM, an 5 MPx camera with auto-focus, a microSD card reader, GPS receiver, 1,230 mAh battery, and a 3.5 mm headset jack.

This HTC device will come with Windows Mobile's standard collection of mobile apps: Outlook, Office, Media Player. Opera Mobile is going to be the default web browser.
