The HTC Radar 4G sports a 3.8-inch WVGA display on a white and silver unibody chassis, featuring a 1GHz Qualcomm Snapdragon processor, 512MB RAM, 8GB of internal storage, a VGA front-facing camera, and a 5-megapixel rear-facing camera that also boasts a 28mm f/2.2 aperture wide-angle lens with single LED flash.

It’s the smaller of two upcoming HTC Windows Phone 7.5 Mango handsets that include the HTC Titan, which features a massive 4.7-inch display. Both phones were first unveiled at IFA 2011, and Microsoft has planned various events in five major US cities throughout the next two months to introduce the phones.

The HTC Radar 4G features a white and silver unibody chassis that sports a 3.8-inch WVGA display, 1GHz Qualcomm Snapdragon processor, 8GB of internal storage, a VGA resolution front-facing camera good for video calling, and a 5-megapixel rear-facing camera with a 28mm f/2.2 aperture wide-angle lens, and a single LED flash. It also boasts a dedicated camera button so that you can quickly access the camera even when the phone is locked.

The nice hardware plus the vastly improved Windows Phone 7.5 Mango update should make this a nice new option for T-Mobile customers. The handset is set to arrive in time for the holidays, but an exact date and price have not been announced yet. For more details on the HTC Radar 4G, make sure to check out our hands-on with the device during IFA 2011. And for more details on the Mango update, make sure to take a look at our Technical Preview.

The device will be heading to T-Mobile as the HTC Radar 4G with support for the carrier’s HSPA+ network. The FCC filings have it listed under model number PI06110, packing support for GSM/EDGE/WCDMA bands as well as the 1700MHz band used by T-Mobile. The device sports a 3.8-inch WVGA display, 1GHz processor, and 8GB internal storage. It also offers a 5-megapixel rear-facing camera with a single LED flash and f/2.2 aperture as well as a VGA resolution front-facing camera for video calls.

Although a release date hasn’t been announced yet, Microsoft has already confirmed that the Windows Phone 7.5 Mango update will be rolled out to existing Windows Phone handsets within the next two weeks. It’s possible that some of the very first Windows Phone 7.5 Mango handsets will be launched around the same time. For more details on the HTC Radar, make sure to check out our hands-on video.

The Radar “will feature in hero POS [Point Of Sale] across all stores and its own demo hub across 150 of Phones4u’s top stores” the company claims, while staff will receive specific Windows Phone training in preparation. That should hopefully address frequent complaints that in-store promotion of Windows Phone falls short of that for iOS and Android devices.

When they all arrive at the beginning of next month, the Sensation XE will be priced from free on a £36 or above two-year agreement, the white Sensation will be free on £31 or above agreements, and the Radar will be free on £26 or above agreements. If you would prefer a SIM-free Sensation XE, however, retailer MobileFun has confirmed that it will arrive on October 7 priced at £489.95 ($775).

Build quality, as we’ve found with all of HTC’s unibody devices, is strong and creak-free. The lower white panel slides off to reveal the battery and SIM card slot, and there’s a dedicated camera key, microUSB port and 3.5mm headphone socket. Size-wise, the 120.5 x 61.5 x 10.9 mm handset is more compact in the hand than the first-gen HTC Trophy, despite offering the same screen size. It also has better viewing angles.

HTC is particularly pushing the Radar’s photographic abilities, with the 5-megapixel camera using a back-illuminated sensor for improved low-light performance. There’s also a 28mm wide-angle lens, together with a single-LED flash and f/2.2 aperture. Up front is a VGA resolution camera for vanity shots and video calls, when they’re supported.

It’s really the combination of HTC’s hardware and the much-improved Mango that makes the Radar a success. Microsoft’s first major update to Windows Phone has, as we discovered in our technical preview, polished many of the rough edges early-adopters complained about; with the Radar expected to be priced roughly in line with the Android-based HTC Desire S, it’s likely to find an audience among those who want to spend less time tinkering with their handset and more time getting on with smartphone features.
