HTC 7 Surround multimedia phone for WP7 is official

Windows Phone 7 handset has unique slide-out speaker

Dolby Mobile-packing handset is US-only

The new Windows Phone 7 range is showing up in all sorts of shapes and sizes, but none quite as unique as the HTC 7 Surround which was launched for the North American territories at the platform's launch today.

The HTC 7 Surround boasts something we've never seen before - a slide up Dolby Mobile speaker unit which slips out of the top of the phone when in landscape mode.

With the HD7, and its 4.3-inch screen, aimed at the movie lovers amond prospective WP7 buyers, there's no prizes for guessing who it's going after with the Surround. For audiophiles it's also toting the SRS Wow HD sound driver and Sound Enhancer app.

The attractive handset boasts a 3.8-inch WVGA, 800x480 multi-touch screen with a kick-stand to add an excellent viewing experience to the obvious audio proficiency.

In terms of the general specs, we've got a 1GHz Snapdragon processor, HD video recording at 720p and a 5-megapixel camera with autofocus, three things present on all WIndows Phone 7 handsets we've seen on launch day.

Obviously there's the OS too, with Xbox Live, a Zune Music player, Microsoft Office and a range of hubs for each of your phone's essential compartments.

It's a shame that this handset is unlikely to make these shores because it's certainly more interesting than some of the identikit candybar touchscreen devices we have to choose from on these shores.

The handset is one of five WP7 newbies outed by the Taiwanese manufacturer, continuing its long-standing partnership with Windows Mobile.
