Windows Phone Mango is coming really soon (this week according to some rumors) and AT&T is here to back that up as the carrier just announced its fall Windows Phone 7 Mango line-up.

Continuing to be the “premier” Windows Phone carrier, AT&T will bring on the newly announced HTC Titan. The phone features a massive 4.7-inch screen, a speedy 1.5 GHz processor and an eight-megapixel camera with dual LED flash that will allegedly take great low-light pictures, aside from the front-facer for video chat.

The Samsung Focus is getting a refresh as the Focus S and AT&T will also carry it. The device packs a 4.3-inch Super AMOLED Plus display like the one on the Galaxy S II, 1.4GHz processor, radio capable of 4G speeds, a front facing 1.3-megapixel and a rear facing 8-megapixel camera. It will have a very thin form factor, measuring only 8.55 millimeters.

Last but not least there’s the Focus Flash, a more budget-oriented device with a 3.7-inch Super AMOLED screen that will reduce its dimensions. Inside it features a 1.4 GHz processor and a five-megapixel camera in addition to the front-facer.

All of the above phones will be available from AT&T this fall, the period in which the Mango update will be delivered to already existing devices: HTC HD7S, HTC Surround, LG Quantum, and Samsung Focus.
