AT&T intros Windows Phone Mango devices from Samsung, HTC

Today, AT&T announced plans to bring three new Windows Phone 7.5 Mango devices to its lineup this fall, the HTC Titan, Samsung Focus S, and Samsung Focus Flash. The carrier did not reveal specific release dates and pricing for the smartphones at this time, but here's a preview of each device.

First introduced in Europe, the HTC Titan offers a 1.5GHz processor, 16GB of internal memory, an 8-megapixel camera, and a front-facing 1.3-megapixel camera. It also features a 4.7-inch WVGA touch screen and will support AT&T's U-Verse Mobile service.

Meanwhile, the Samsung Focus S improves on last year's Focus model by adding a faster 1.4GHz processor and a larger and sharper 4.3-inch Super AMOLED Plus touch screen. The handset also has a rear-facing 8-megapixel camera and a front-facing 1.3-megapixel camera for video calls, which is a new feature of Windows Phone 7.5 Mango.

Last but not least, the Samsung Focus Flash will be for those looking for a more budget-friendly option and comes with a 3.7-inch Super AMOLED display, a 1.4GHz processor, a 5-megapixel main camera, and an unspecified front-facing camera.

AT&T said all three handsets will be 4G devices, which we're guessing to mean HSPA+. In addition to the new phones, the carrier confirmed that it will update all of its current Windows Phone devices--the Samsung Focus, LG Quantum, HTC Surround, and HTC HD7S--to Mango this fall, but again, no specific dates were given.
