Facebook on Thursday denied earlier reports that HTC is preparing to unveil multiple Facebook-branded smartphones next month at Mobile World Congress. “This is really just another example of a manufacturer who has taken our public APIs (application programing interfaces) and integrated them into their device in an interesting way,” Facebook’s head of business development Dan Rose told reporters.”The rumors around there being something more to this HTC device are overblown.” Rose did not comment on whether or not Facebook is currently working on branded cell phones without HTC’s involvement.
