AT&T-branded Samsung Omnia in the works?

LG and Samsung just love throwing down the touchscreen gauntlet on American carriers lately -- one only need look at the Dare, Instinct, Vu, Voyager, and Glyde to figure that much out. Thing is, none of those devices really fall into the smartphone bucket, much less the coveted "superphone" one. That might just be where the recently-announced Samsung Omnia comes into play, though, which is now rumored to be destined for AT&T with a gaggle of features in tow: Windows Mobile 6.1, 5 megapixel camera, HSDPA, at least 8GB of internal storage, and support for AT&T Mobile TV. If it turns out to be true, that's got to steam LG, who's presently sitting atop the AT&T Mobile TV food chain with the Vu -- but hey, if that means they're going to set to work with another range-topper above this one, we're all for it.
