In May Microsoft previewed the first major upgrade to its rejuvenated mobile OS. Mango will bring multitasking, IE9, and deeper social network integration, among other things, to Windows Phone 7 devices. This fall, AT&T intends to upgrade their entire WP7 portfolio to Mango. Nice! But there’s more. In a press release (in full after the break), Ma Bell also announced three brand new handsets that will ship with Mango on board in Q4. The new and improved Samsung Focus S features a 4.3-inch Super AMOLED Plus display, 1.4GHz processor, a rear facing 8 megapixel camera and a front facing 1.3 megapixel, “4G”-capable speeds, and a thin profile at 8.55 millimeters. The Focus Flash downgrades things a bit and packs a smaller 3.7-inch Super AMOLED screen, a 5 megapixel camera with front facing camera, but it keeps the speedy 1.4 GHz processor. And finally the large-and-in-charge HTC Titan features a 4.7-inch display, 1.5 GHz processor, and 8 megapixel camera with dual LED flash. Pricing and exact available will have to wait.

Update: Microsoft shows off a bunch of Mango’s new features in dramatic video fashion after the break.
