AT&T announces Windows Phone Mango lineup coming this fall, existing devices to be updated

In the first of what we expect to be many announcements related to Windows Phone Mango devices, AT&T stepped up to the plate this morning by unveiling three new “4G” handsets that use the latest version of Microsoft’s OS: the HTC Titan, Samsung Focus S and Focus Flash. We already know quite a bit about the Titan, but details on Sammy’s selections are slim for now — images aren’t even available for either phone, though it’s likely we’ve seen at least one of them before. In addition, the carrier’s also planning to update its entire existing lineup with Windows Phone 7.5.

As for the fall lineup, there doesn’t seem to be a slacker in the bunch. The Focus S will have a 4.3-inch Super AMOLED Plus display, 1.4GHz CPU and an 8 megapixel rear camera that accompanies a 1.3 megapixel front-facing cam for video chat. Also bearing Mango is the Samsung Focus Flash, considered the lower-end offering by Sammy, which still brandishes a 3.7-inch Super AMOLED screen — no Plus involved on this one — as well as a 1.4GHz CPU and 5 megapixel rear shooter and front-facing camera that for now has no specified resolution. Each of the phones are expected to arrive in the fourth quarter, and the existing lineup should be on the receiving end of the update sometime “this fall.” This
