The phones will be the first to sport Facebook’s official colors and branding, according to City A.M. And in line with previous rumors, Facebook’s phones will run on modified versions of Google’s Android OS.

The Facebook phones are expected to make their first appearance at Mobile World Congress in Barcelona next month. City A.M. has a good track record on mobile phones: it was the first to break the news of the second-generation Google Nexus phone.

The HTC devices will reportedly include Facebook integrations that will make it easier to call and message your Facebook friends. They will also prominently display the news feed on the home screen. We’d expect any Facebook phone to also include Facebook Chat, Messages, Events and Photos integration.

Last year, the rumor mill went wild about the potential launch of a Facebook phone. Facebook has repeatedly denied that it was working on a phone. Even Mark Zuckerberg told us it wasn’t in the phone business when we interviewed him last year. While Facebook won’t technically be manufacturing a smartphone, it still is an about-face from its previous statements, if the report is true.
