HTC hit a grand slam homerun at Mobile World Congress in Barcelona Spain earlier this year. They introduced the HTC Flyer tablet, and a whole slew of phones including two Facebook integrated phones. The Facebook phones announced were the HTC Cha Cha and the HTC Salsa.
Pocketnow was able to dig up HTC’s filing for the HTC Cha Cha off the FCC website. Although the HTC documentation found pertains to the European version (model number PH06110), Pocketnow reports that another model (PH06130) “has the markings to be the model that will make it to the US on AT&T”
AT&T was rumored to be the carrier of the “Facebook” phones dating back to MWC.
