HTC's One-Button Facebook Phones Headed to AT&T

Yesterday HTC unveiled two new Facebook Phones, and now US mobile operator AT&T has announced that they will be selling HTC Facebook Phones later this year, although they didn’t specify that it would be the HTC Salsa and HTC ChaCha.

So does HTC have some other Facebook Phones in the works, or will these be modified versions of the HTC Salsa and ChaCha for AT&T?
“In the U.S., AT&T and HTC are exclusively bringing this unique user experience to the market later this year,”

It is not clear form the AT&T statement, but we suspect they will be AT&T branded versions of both of these new HTC Facebook phones. We know that AT&T plans to launch quitye a few different Android devices this year.
