The onslaught of Windows Phone 7 handsets has just begun and we’ve had our hands on the much leaked and rumoured HTC 7 Mozart.

We’re trying to figure out exactly why it is named after one of the World’s greatest ever composers. We can’t see a link to D major, it certainly wasn’t completed in 1768, but there might possibly be four movements, like Mozart’s Symphony 7.

Perhaps it’s just down to the Zune integration and the Dolby Mobile and SRS WOW HD integration. But then that’s something common to all of HTC’s new Windows Phone 7 handsets.

The HTC 7 Mozart features an anodised aluminium unibody. It has a 3.7-inch capacitive touchscreen display with WP7-specified 800 x 480 pixel resolution.

It measures 119 x 60.2 x 11.9mm, and feels good in the hand, with that anodised body reminding us of the HTC Desire. It also shares some detailing with the HTC Desire - the rounded edges especially.

Internally you get a 1GHz QSD8250 processor, 512MB ROM, 576MB RAM and 8GB of storage. You get all the normal connectivity options, with HSDPA, Bluetooth 2.1, Wi-Fi b/g/n.

Around the back is a big, bad 8-megapixel camera with a Xenon flash and autofocus, which also offers 720p video capture.

The strangest thing about the HTC 7 Mozart is the detailing on the back. It’s almost as though the Mozart is wearing a pair of metal pants, with the black rubberised butt cheeks hanging out of either side. We’re guessing this is to ensure excellent reception, but it certainly made us chuckle.

In the UK the HTC 7 Mozart will be an Orange exclusive handset (as previously leaked by them), and will broadly appear as an Orange exclusive handset across Europe. 

Hopefully the phone will be classic instead of pants. Whilst we ponder that point, check out all our hands-on photos.
