The Newest Windows Phone 7.5 smartphones

Can new designs and the latest OS spark buyer interest?

Microsoft's new release of the Windows Phone mobile OS, 7.5 or " Mango ,"  is getting some good reviews. The new OS version, with its distinctive, fluid Metro UI, features hundreds of changes, including more dynamic, and more customizable "Live Tiles" (shown). For more details, see " Windows Phone 7 Mango: A Visual Tour of the New Features"

Some of the "new" Windows Phone 7.5 devices will be the existing models that download Windows Phone 7.5, formerly dubbed Mango. But a new crop of phones to exploit it are also starting to appear, here and abroad. Here's a quick overview of them. In most cases, prices have not been announced.

Fujitsu Toshiba IS12T:

Fujitsu Toshiba IS12T: The very first Windows Phone 7.5 handset was unveiled for Japan in late July: the brilliantly-colored but dully-named IS12T, from Fujitsu Toshiba. Dimensions are nearly identical to iPhone 4, but it weighs one ounce less; 3.7-inch screen, 480 x 800 pixels. It's water- and dust-resistant (carrier KDDI's website cautions  "Please do not soak in the spa pool water." It sports an astounding 13.2 megapixel camera and 32GB of storage.

HTC Radar 4G:

HTC Radar 4G: The HTC Radar 4G has 0.43-inch thick metal unibody design. It's not a techspec pathbreaker: 8GB storage, 512MB RAM, 3.8-inch screen with 480 x 800 pixels, 5 megapixel/720p camera with LED flash (plus front-facing VGA camera for video chats), Qualcomm's Snapdragon processor at 1GHz. Radar will be available on T-Mobile's HSPA+ 14.4 “4G network. (1 of 2 slides)

HTC Titan: This aptly named device is a high-end Windows Phone: a titanic smartphone screen at 4.7 inches, 480x800 pixels. Dimensions are 5.18 x 2.78 x 0.39 inches; weight with battery, 5.6 ounces. The processor runs at 1.5GHz and the phone boasts an 8-megapixel camera and a 1.3-mp front-facing cam. Other stats: 16GB storage and 512MB RAM. AT&T will have it later this fall. More info.

LG Jil Sander:

LG Jil Sander: This phone carries the name of a leading German fashion designer , bringing some haut couture to the original LG Optimus. According to PocketNow, which scooped the specs , the Jil Sander model is a bit larger than the original, but just over a half-ounce lighter. It’s expected to have apps and content from the designer.

Samsung?s Focus Flash

Samsung’s Focus Flash: As of this posting, no photos have surfaced of this device. But some are saying the just-unveiled Samsung Omnia W (the photo shown here, and see slide #8) is the overseas version of this model. Its 3.7-inch screen is a bit smaller than the first Focus, but is features a Super AMOLED display, and a faster processor. AT&T will offer the Flash later this Fall.

Samsung Focus S:

Samsung Focus S: In July, Microsoft briefly teased a conference audience with this device, generally agreed to be the new Samsung Focus S, on AT&T. Many are hoping it will a Windows Phone 7.5 version of the wildly successful Samsung Galaxy S or S II. Focus S will have a 4.3-inch Super AMOLED screen, 1.4GHz processor, 8 megapixel camera (and a front-facing 1.3 megapixel cam). It will be just 0.33 inches thick and support “4G-capable speeds,” which almost certainly means AT&T’s HSPA+ network.

The Samsung Omnia

The Samsung Omnia W (which is possibly also the Focus Flash destined for the U.S.): It packs a lot into its 4.55 x 2.31 x 0.43 inch frame: a bright, crisp Super AMOLED screen, 3.7 inches, 800 x 480 pixels; 8GB storage, 512MB RAM, 5 megapixel camera with LED flash and front-facing VGA cam, and a 1.4 GHz processor. Overseas, it’s priced at about the equivalent of $422, before taxes and subsidies.

ZTE Tania:

ZTE Tania: One of the new Windows Phone manufacturers is China-based ZTE, which has unveiled the Tania (you won’t find it in the U.S.). It’s clearly designed to make smartphones attractive and affordable for first time buyers. The 4.3-inch screen has 400 x 480 pixel resolution. Tania supports HSPA+, and has 512MB RAM, just 4GB of storage, a 5 megapixel camera, Wi-Fi and assisted GPS.
